I need someone to talk some sense into me. My bf's friend died about a month ago - I didn't know him - and since then he has been supporting his friend's ex gf with her grief. They message every day and he is seeing her for coffee on Saturday. I'm not usually a jealous person but I do feel uncomfortable about this as I know they can bond over their grief and I am worried it could turn into more. He has given me no reason not to trust him so I don't know why I'm feeling like this. Any advice? I feel like I need to get my worries out here rather than bringing them up to him. I have been doing my best to support bf with his grief - listening to him, cuddles, getting him his favourite snacks etc.
