Am I being controlling because I don't want my girlfriend to spend too long on her phone when I'm with her?
what exactly do you want to talk about with her?
Nothing particular. I just want her to pay attention when I'm with her.
Your expectation from your girlfriend is very reasonable. It's rude on her part to be on phone when she's with you.
I think my girlfriend is a slut. She always hanging out with her friends on the phone when I'm with her.
That's a terrible name to call her and its very demeaning to say that just because she is talking to her friends. While I get why you want attention from her I think you need to stop using language like that towards her.
