He left her for me 4 months ago. Now and than he mentions her and i really didn’t mind. But few days ago he literally mentioned her in every single topic and i told him i don’t like that. He said sorry and said i am right but he said it means nothing just a coincidence that these specific topics lead to him remembering this or that. How should i deal with it? I know he got no feelings for her but it really makes me uncomfortable.
