He just thinks he’s so hot that she should be happy to be with him. He’s a total loser who doesn’t want to work and prefer to blame you for having “expensive” taste to belittle her.

My ex was like that. I earned way more than him and he lived in a crappy room with roomates in London while i lived in France in a nice brand new flat that i bought by MYSELF. He kept telling me i wasnt good enough , kept giving me the cold look as soon as i told him i bought myself something nice. He was bringing money around for every single topic . I could have said something like i didnt liked Mcdonald and he would just reply " yea of course because you’re to good for fastfood" (while i LOVE a good kebab or burger king).

He was trying to make me feel like shit all the time.

Those guys love to make a girl insecure about herself , and they will target the ones that are confidents and successful. They are “proud” to have those girls on their arms because they can brag in public but behind close doors its an other story
