Okay, from a dude (aka me)
1. She isn’t being honest or transparent
2. She doesn’t respect your boundaries or privacy, and this goes both ways
3. She starts making fun of you for gaming and having fun. (There is a difference between being a regular gamer and an addict who does nothing but game all day and is a bum)
4. She doesn’t take care of herself (This also applies to us guys, we gotta all be hygienic)
5. She starts being fake and not herself. Literally don’t try to be someone you are not, being a poser is the worst thing you can do.
6. Being a Gold Digger (I don’t think that one needs to be explained, no one likes a Con Artist)
7. She puts you down and shames you for being yourself. There is a difference between being strict and actually caring for someone, and being a bitch.
