My girlfriend of 6 months still regularly chats to her sex buddy who she had between our relationship and the last one. I told her before that I'm very uncomfortable with it but she says I then put her in an awkward place as they were friends before. He is 24 she is 46 and I'm 43. I know a lot is my insecurity but she as much as said he knows nothing will happen while we are together. It then sounds like she's keeping him in reserve in case we split. It does seem very disrespectful in my eyes but am I thinking about it wrong? She has said I can see their texts but I don't know whether I should out of either respect for her or in case I see something I don't like. It's just that he messages her "what you doing this weekend? " and I really hate it
