Please help. So I split with my husband and met someone also separated. I then found out they split as she hates sex and he had an affair. Not with me. I would never have done that. He lost his mum youngish and she is older. We were together about 6 years and then they started to meet up and here is my issue. She totally pretends I don't exist. We are now 8 years later and he still meets up with her and she still pretends I don't exist. She has not had another partner. He doesn't think it's an issue but I do. What do you think?
