Sorry Kev, our posts crossed.
Keeping things simple is probably best for now. There's nothing wrong with being friends with the aa guy. But if he's going through a break up and you're working on your relationship with your bf, emotions can become confused and confusing. Think of it like your decision to stop drinking. Don't doubt the decision. You've decided you want to be with your bf. That's your decision. However confused you may feel, keep thinking back to that decision xx
