First and you started dating 1 month ago, you love him very much and tried to be the best girlfriend/boyfriend for him. But does he love you?

First dates, but breaks up with that person after a month or two. He thinks relationship is a joke.. He plays girls/boys and acts like he is in love with that girl/boy, but he actually isn't

You transfered to a university, not knowing he is also in that university. You guys are in the same class, and nobody warned you that he is a playboy

You met a few friends and built a strong bond with them. One of your friends warned you about First, and you thought she/he was joking so you didn't take that warning seriously

First suddenly asked you out and you agreed. And, it's alright, but everytime your most close gbf comes, he completely ignores you

Days passed, and he is now fully ignoring you, he is always on his phone, going out, and hanging out with your gbf.

2 days before your b-day, you invited your gbf. She arrived and you both talked, you left to go to the bathroom. When you came back, you saw her and First being intimately close with eachother
