You pose an excellent question. It can't possibly be good thing for you to work so hard to feel so positive about yourself, only to have his presence trigger all those negative feelings you've worked so hard to overcome. Over time, and as your self esteem continues to grow, it seems logical that you won't care as much about what he thinks, so he will likely have less and less of a negative effect on you. I don't know what your long-term plans are, but personally, I would stay away from him to the extent possible. I hope you're feeling better and haven't dwelled on him too much since Thanksgiving -- as you know, life can be pretty darn good!
