That indifference bit may never go away. It can be ignored and forgotten about but sometime something will remind you and it will piss you off all over again but that feeling will go away quickly once you get away from the thing that triggered it.
One thing I want to say is don't ever blame the other woman. It was entirely your husband's choice/ fault. He could have said no. I HATE it when women say 'she broke up my marriage, 'she chased/seduced my husband' while the man sits back & sighs 'I couldn't help myself - she came on to me' . It's all him. She did you a favour.
@onlyduh Sorry but still no. He made the choice to betray you. He was the one in a supposedly committed relationship. If it wasn't her, it would have been someone else. You can't blame all the women in the world. He is the constant in this, she is just the variable. If you make it me & them, you increase your pain. Me & him is more straightforward. And he'll probably do the same to her in time. She didn't get anthing of value. I pity her. Reason I'm saying this is because if you look at it this way, it immediately halves the resentment, pain, anger etc so you have less to deal with. I'm on your side.
@onlyduh Not forgiveness. Just indifference. I wish you well. X
@onlyduh - Great! First one left me to become "a full time worker for god", second one addled his brain so much with alcohol he didn't know who I was! Can't wait for the chat room!
