So my SO has had a past of cheating. I wasn't made aware of that until I caught him back on his dating profile last year messaging 15+ different women basically begging for nudes. I'll add that I was pregnant while he did that, found it all 4 weeks pp. Well I was standing in the kitchen drinking my coffee when I just happened to look his way and glimpsed what he was doing on his phone. When he heard me take a step his way (didn't know I was looking), he slowly lowered the phone screen down in his lap. I waited til he went to the bathroom and typed the site in my browser and guessed his login info. It's an alumni site from his high school that is basically like a knock off Facebook, you can post stuff and message people. His relationship status was set as single and his number of children was 0. There were no messages on it (dunno if he deletes them) but there were 2 notifications of some girls looking at his profile. I recognized them from his phone last year on Facebook messenger (when I found the dating profile I hacked into everything of his, yes I'm a tech psycho when I get messed over sns 🤷), before he dated me he had hooked up with them on several occasions. I'm not wanting to jump to conclusions and make him mad, but should I keep an eye on this? I'm not the type to keep him away from old friends, even girls, I just don't like the thought of him trying to keep in touch with past sexual partners I guess.
