Hi.  I am brand new to this site and am not sure how things work here.  I have a big problem and I need some insight.

I have been in a five-year relationship with a recovering Meth addict who also took Rx drugs.  From the beginning he lied to me about his marital status and said he was divorced.  Later I found out that he was still married, but separated.  His wife is a hard-core alcoholic and the family unit was not a happy one, from what I've been told.  It was almost a year into the relationship when I discovered his addiction.  I had never known any addicts and had no idea what to look for in their behavior to suggest addiction.  By the way, this was a long-distance relationship and I spent many hours traveling to visit him because he was tied down taking care of his elderly father.  His addiction progressed to the point that I had made the decision to stop seeing him and told him that if he ever came to my home high or with drugs on him he would be arrested.  He chose to ignore that warning and did both things.  He came to my home many, many hours later than he had promised and he was extremely high.  I did as I promised I would and had him arrested.  He spent several days in jail with a huge bond ($400,000) because he was from out of state and considered a flight risk.  He had Rx drugs that belonged to his father, no insurance on his vehicle, a crack pipe in his vehicle and he had a tag on his vehicle that belonged on his father's car.  His family supported me and said I had done the right thing by turning him in because he was on a downward spiral toward death and would have been dead within days or weeks if I'd not had him arrested.  He also agreed later that I had saved his life. 

While he was in jail I supported him by purchasing all of the items he needed (T-shirts, socks, underwear, toiletries, cigarettes, etc.).  Once he left jail he volunteered to check himself into a 30-day rehab program and he completed that.  While he was in jail and rehab I was the only visitor he had and none of his family came to see him.  He called me collect every time he could and that ran my phone bills up.  I also supported him while he was in rehab. 

After rehab he had trouble finding work so we uprooted and moved to another state where no one knew him.  We used my credit cards to the point of maxing them all out and stayed exactly one year.  He is also running from the IRS for not having filed a tax return in several years.  We moved back to my home and he secured a job 70 miles from home where he'd worked until he left two weeks ago. 

Now, let's fast forward to June 3, 2011.  His son was getting married and I did not get along with the girl his son was marrying.  Over the past six months there had been bad blood brewing between his daughter and me because of some stupid stuff on Facebook.  I was not invited to the wedding and my ex refused to tell me when it was and always pretended to not know the date of it.  He hid the invitation in his vehicle and I never saw it.  Every time I'd ask if he was planning on going he would say he had no plans and had not talked to his children.  I was in a neighboring city with a friend on June 3 when he called me to say that his son's wedding was the next day, June 4, and that he was going.  I was shocked.  After all, I'd asked him several times over the course of the two months since he'd received the invitation when it was, etc, and he lied about it every time.  He was halfway to the city (5 hours away) when he called to say he was going.  We had a few words about it and my feelings were totally crushed.  After all I'd done for him when none of his family, even his children, would help him or visit him, he did this to me.  Behind my back.  The last time I spoke to him was about 9:00 PM on June 3 and he said he was coming back after the wedding on June 4th because he had to work the next day. 

He has not spoken to me since.  This man treated me very well while we were together for 5 years, saying and acting like he truly loved me.  How could he walk away and never even speak to me again?  I helped him save his life.  I helped him regain his life.  He never wanted me to work so I have not worked in more than 3 years.  Every bill we had is in my name; electricity, gas, water, phones, insurance, etc.  I tried three times to call him on Sunday, June 5, and sent three text messages.  He never returned either.  I emailed him and instead of him replying, his daughter did.  After 9 days he finally emailed me a very brief note saying to get rid of his belongings.  He left behind heirlooms from his deceased parents, baby pictures of himself, some of his tools, almost every stitch of his clothing, one of his guitars (the one I bought for him while he was in rehab).  From what I can tell all he took was his suit, his electric guitar, some tools and the laptop.  He spoke to my son telling him he'd call me but he didn't.  He also told my son that he was having "urges" and needed to find a meeting.  My son said my ex told him he felt torn between me and his kids and that my ex was crying (he never cried).  It has now been 16 days since I've heard his voice and I don't expect to. 

The day he left he was telling a neighbor (a very casual acquaintance) all about his addiction and it seemed as if he was almost boasting in the way he was telling it.  I was pretty shocked that he'd tell someone he barely knew about how much of a "hard core" user he'd been and how he knew how little it would take to make his world perfect again, etc. 

Does anyone have any insight as to what may be going on?  Does it sound like he may be using again?

Remember, we had an almost perfect relationship for 5 years.  We didn't fight and rarely had a disagreement.  He was stressed at work, but other than a few financial difficulties, our relationship was good.  How could he just walk away from that and go back to where all of his problems and his addiction began?  PLEASE HELP ME TO UNDERSTAND THIS!  Thank you to anyone who can help.  I really am going crazy thinking about what could have happended and why.
