Dating

Is my girlfriend crazy or what?(sorry for the long paragraph in advance)?

Okay so about a month ago, my girlfriend and I got in this huge fight over her brother girlfriend leaving him for my guy friend and she was upset with me because, she thinks it’s not okay for a sophomore to be dating a junior and calls me weird for being friends with him. So later, on she decides to break up with me cause she blames me for telling her it’s not our problem with what happens between her brother and my friend beef or whatever over some girl. After she broke up with me, a fews days went by and I found out she had been texting these freshmen guy. She claims “if your friend can do than so can I” and so I asked, “why should it matter wtf my guy friend is doing” and she said some lame excuse to cover up her ignorance. Anyways, a month went by and I’ve been trying to win her back ever since that day happen and trying to understand why she’s been treating me like shit for example, she’s been messing with other guys and telling me how she feels about them then, becomes mad when I tell her about girls I’ve been messing with. To sum this whole nonsense up is she’s been being a hoe and later this day I was finally ready to move on and she suddenly texted me tonight telling me how much she “miss me” following Up with calling me “bae” and suddenly being lovely again out of the blue.
