Hi, I'm new to this and was looking for some outside advice!
I was seeing my now boyfriend for about 6 months before we became an item. During this 6 months he constantly talked about his ex girlfriend. He was broke up with her about 3 years at the time but was in a steady 4 year relationship with her. Every single day we were together he would always bring her into almost every conversation. I now know pretty much every detail about her without even meeting her! I even know what moisturiser she wears due to him telling me one night. Since we became an item he never mentions her. I confronted him about it lately and he said he never taught we would end up in a relationship, we both just taught we were having fun at the time!

Am I crazy to be extremely insecure about his feelings for her? I find myself constantly questioning myself wheither he still has feelings.
