I'm plucking up the strength to end it with, let's call him D for dickhead tonight.
He's cheated on me. He's sorry but not done anything I asked over the last 4 weeks since I found out, if it was hard or uncomfortable for him. . Plenty of DARVO. I've looked at Chump lady, which helps, especially around trying to figure out the why (he says he doesn't know). She's right, it's simple, he had the opportunity and he found it enjoyable.
This is hard. I do still feelings for him. I face starting all over again in mid 50s. When I retire I'll be very hard up on my own. This is scary.
