Need to vent please listen

Okay so I'm in a long distance relationship and we are both in college. My bf had his first day yesterday and this girl and him did hw together. Okay I trust him and all but hear me out... my bf hates school, he always saves hw for last minute, I usually have to encourage him to do hw!! I met the girl he was with before but still come on. I'm not gonna be petty but I had plans to study with a guy in my class so I may tell a little white lie just so he knows I can play the game too. Ik some people will say don't but the other day he was like why would you give him your number and all and I was like well because it's a hard class and he seems normal and Ik he has a gf so he won't hit on me. Just pisses me off because he makes it a big deal
