Pics with his ex

I found some pics my bf had of him and his ex in his room. (Long story short, he didnt know they were there and he threw them away after, ressasured me that was his past and dont).

Anyways, the issue is I (the curious person and self torturing person I am) went through them. It made me so sad and jealous obviously to see those pics of them together, looking cute and happy. And pics with her and his family. But the one that got me was one of him planting a huge kiss on her cheek. This one in particular caught me because its a picture I’ve never been able to get with him. He’s never been so lovely dovey with me in a picture (minus one where he was drunk and kissed me on my cheek and his mom got a picture). Our pics usually consist of plain old selfies that I mostly insist on taking. Or pics of me planting a kiss on his cheek.

It just hurts to see that and think, “why isnt he like that with me?” “why can you clealry see so much love in that picture and not with ones I have”

They broke up about 4 years ago, and my bf and I have been together a little over a year. They were together a little over a year also I believe.

What makes me overthink is the fact that this was the girl he told me broke his heart and took him a long time to get over. It just makes me compare and think if he doesnt show that same affection because he doesnt feel it.

Thoughts? Anyone go thru something similar?:(
