Morning Coffee Cheater

My boyfriend usually sleeps in my room unless there is a party at his fraternity and then we usually just crash there. Anyway, he is always leaving at 8 on tuesdays and thursdays but his class those mornings doesn't start until 11. He says he goes to the gym before class but I followed him this week.

Both days he never went to the gym. He went to the coffee shop on campus and met up with this girl I don't know (and I won't lie - she's hot). He sat there with her and they were definitely not studying. Flirting hard! They talked for 2 hours and then hugged when she left (a looooong hug) and I think he patted her azz a couple times.

So I asked him after class how the gym was. I'm sore is all he said. WTF! He lied. So I tell him I know. He said I wouldn't understand about Katie and they were just friends. I said it would be fine if you told me about her but now I don't trust you with her so you can't talk to her. Now he's mad at me. Who's right?
