eee, ROOT is right, time is the real healer. I can totally relate to the sadness and insecurity. My H's A is also over, and I know a lot of the details, too. We are definitely on the road to R. But those feelings of sadness, thinking of what he did, how much he hurt me, etc. do haunt me from time to time. It's been several months for me and it does get better. Again, time will heal.
But what I haven't done, and need to do, is talk more to my H about these feelings. I'm with you, I'm afraid to do it. But I know I need to. He's probably not going to be really thrilled at the conversation, but I'm afraid if we don't, I'll never be able to air my feelings and in the long run, I'll regret it! I don't want these long months of DBing to be in vain. Communication is so important!!!
I also try to focus on the here and now -- and the future. The A is over, we're back on track and the past is the past. I know the time will come to share my feelings with him.
I hope Saffie stops by. She's a long time poster who joined the board for this very reason -- just dealing with and moving past all those feelings.
