I've been with my partner for a year now and he still meets up with his ex wife for a catch up every few months. They split up 5 years ago. He knows I feel really uncomfortable with this situation but still he insists on seeing her. I know he feels a lot of guilt about cheating on her and feels like he needs to look out for her but I can't explain it, my stomach just gets into knots and I get extremely anxious before he meets up with her until I hear from him after they've met. I am constantly expecting him to tell me they're getting back together. He's seeing her tomorrow night and I can't sleep. He knows I'm in a state about it but he will not stop his plans to see her. He tells me that I knew he's still friends with her from the start of our relationship. He did tell me from the start that he occasionally speaks to her but I didn’t realise until 3 months into our relationship that they still meet up occasionally. Am I being controlling asking him not to meet her?
