This definitely a strange behavior, it’s normal for people to change some when they start seeing someone new but being argumentative is strange. There’s a chance she’s projecting for anger in the relationship at you or maybe she’s become a bit insecure since something the relationship and is lashing out. I think you should talk to her, this isn’t a sustainable friendship otherwise. You don’t deserve to deal with a person who’s hot and cold
I think that people can be happier and more confident around their partners and there’s nothing wrong with that but it shouldn’t be done at your expense. Is she no longer making efforts to connect with you? I know you said she’s being shitty but is her argumentative approach and change in personality the only things different or does it extend to her general treatment of you
Well I think that’s the only thing, she’s been hanging out more w different people because I was encouraging her to network bc her mom was complaining to me about her being selfish and lazy and that she doesn’t use her college money to its fullest. But I will say that has come at the expense of the time she spends w me
