I just need a bit of advice and perspective please.
Me and my partner both work for the same company which has many sites all over the region so we sometimes see each other at work or meet for lunch time coffee . The problem I have is his ex works for the company too. I don't know her as the organisation is huge and I don't know many people outside of my team. I know he is still in contact with her, he says its for work but she has nothing to do with the area he is in. He had an on off relationship with her for about 8 years before we got together, he had relationships in between seeing her and this is what has made me so paranoid as I'm not convinced he is totally over her. She is married with kids so she was actually having an affair with him which he seemed ok with and he has said that he is never going back there but something just doesn't seem right to me. I've tried to talk to him but I don't want to keep going on about her in case it pushes him away as it has caused arguments before. I've been with him a year and I do love him but I'm not sure I should trust him.
