<human>: I got out of a rough marriage and have two small kids. I ended up getting back in touch with a boyfriend from my teenage years (10+ years ago) and we started dating again. He's a great guy, amazing with my kids, super affectionate and sweet etc. 

Now, I've never, ever been the jealous type, but he dated one of his good female friends prior to me. He was completely in love with her and wanted to marry her and she broke off the relationship. He doesn't deny he still loves her (but says that he loves me more). He told me the other day that he keeps a video he made of all of their photographs etc. I let him hang out with her alone but I admit that part of me is jealous. I know he had feelings for her and those feelings will probably never go away. Do I ask him not to hang out with her alone? Do I just accept it? Has anyone been in this situation and can you offer any advice?

<bot>: Is it normal for your bf to hang out with his ex who he was (and maybe is) madly in love with?
