I have been with my husband for 21 years and am considerably older than him. He got very friendly with a woman at work and they were texting each other. I found out and we had a major fall out over it. He has promised to break all contact and had even moved to another branch to avoid contact. He assures me that it was not physical and has accepted that this was unacceptable behaviour, and has promised never to do anything like that again. My daughter( from a previous marriage) thinks I should leave him and has actually sent me a text stating that if I stay with him she cannot be a part of my life. I am late 60's and apart from this have had a very happy marriage. I feel that my daughter is way out of order and emotionally blackmailing me. I have decided to stay with my husband but I am mortified that I am losing my only child. She herself has had many relationships that have never worked out and I have always supported her unconditionally without judgement. Can anyone advise how to get this issue resolved.
