Am I wrong for not wanting to talk to her anymore?

So I have been good friends with this girl now for about 2 years and it’s had its ups and downs and she text me and calls me all the time. However recently she told me she’s going to visit a guy friend and stay with him for a week and I just feel like I don’t agree with it because if something were to happen between them I’d be really upset (childish I know) but I do understand I can’t tell her to not go because She’s her own person so I won’t. she said she doesn’t like him but obvi enough to visit and his girlfriend just broke up with him. I have told her I don’t like it and think it’s weird because she’s only known him not too long. So I’ve told her I can’t and will feel bad for ignoring her but I feel I need to put me first because it’s been driving me crazy over the thought of her trip because I guess I like her. Any advice?
