Relationships With Recovering or Non-Recovering Drug Addicts, Anyone With Experience?

I fell in love with someone who was freshly detoxing from an opiate addiction. He switched his attention towards our relationship instead of focusing on his recovery. I had never before met anyone with an addiction problem of any sort so was totally naieve as to getting involved with him, or not to. I know we honestly loved eachother, but I definately put up with some sketchy behavior. As my therapist would say, “I couldn’t see the forest through the trees”, I was totally caught up, or maybe what I have now learned, codependent??? Anyway, we continued a relationship for almost 2 1/2 years, a 2500 mile apart, long distance relationship, so I continued with my life & he claimed to be seeking recovery & getting his shit together so that we could eventually be together. Another thing I have to add is that we fought quite often & I said some VERY MEAN THINGS, & will never forgive myself. He commited suicide after relapsing with heroin & meth on 2/29/08 & I feel GUILTY. Any words?
