This is the absolute truth, as hard as it may be to hear. Some sober alcoholics are not emotionally capable of becoming close to another human being. They are able to stay sober, and may work a program, but they can't seem to "connect." I'm not saying your boyfriend is that way, but he may be. You'll have to do some thinking and decide if you're willing to accept what he is able to give you. A lot of us seek what we need emotionally in people who are unavailable. On the other hand, he may just be going through a difficult time and he may snap out of this. Without knowing him or you, no one can decide that for you. As they say, more will be revealed. Hang in there and I hope you find peace.
