My husband and I have been together 7 years and married 4. We have a 13 month old son together. My husband just started college this summer semester. He's getting his associates finished. Anyway lately he's come home and mentioned some girl in his class a few times. "Me and this girl in my class always laugh when the teacher says that" Stuff like that. This week he said this girl started laughing in class out of nowhere and when he asked her why it was some funny cat video and she showed him. Then he said that she told him she'd put it on her Facebook so if he wanted to see it again or show me he could. I was like wait, you have her Facebook? Then yesterday he was late coming home from his group project at his school library and come to find out this girl is in his group. He told me she was. I'm getting REALLY upset. Part of me is trying to stay rational, he's never cheated and if we was going to why would he talk about her. But the other jealous side of me is like why the heck IS he talking so much about her. Advice needed!
Am I being paranoid or should I be worried?
