((((((((((BH)))))))))))) I just read your last two pages. You are amazingly strong. I am touched by your sharing, & honesty.
I don't think men do things out of "guilt", so I'd look at the same gestures as kindness. Also, the love can come back.
I think you're on the right track of be the best you can be. Fill your own love bucket. Ignore the OW. Try to be the person H fell in love with. I'd also keep up with the mystery. Whether he shows it or not, it should be making him think.
M 19 years, MC for 8 months, DB'd for 8 months 4 kids; 18, 15, 14, & 10 I was never meant to be a doormat. It took me years of therapy to become assertive enough to stop his abuse.
