At a crossroads...

Courtney
My SO was engaged to another girl for 2 years before he decided to break it off. She did not see them as being over even a year after he ended it and moved on to be with me. She kept getting in the way of our relationship and I made him block her from all social media, email, etc. I was tired of having her get in the middle. I thought that would be the last I'd have to hear of her (for the most part). Now she's coming up in every conversation and he still has gifts and cards she gave to him. I know that they're not together but maybe my SO still has feelings for her? Or I'm just over analyzing this? He says I'm his whole world and that he loves me. I don't know what to do or how to approach him about this. I also think maybe he's just trying to get everything she did to him off of his chest and letting me in by sharing some of that?
