I'm sorry to hear this, but don't give up. I've had failed relationships, most of which I look back on with fondness. Very few were horrible mistakes. There were some I wished would never have happened. But here's the best part of your post:
So I'll keep my recovery program strong, try not isolate from people and try my best to understand that I put myself out there and that it was brave to do it.
This is maturity, and you have accomplished an important goal in recovery. What's most important is how you deal with bad situations like a broken romance. Recovery is about learning to deal with stress without running back to the bottle. When you can do that, I say get back out there and keep looking for that right person. Recovery is not be about cutting yourself off and isolating. It's about living life sober.
