For context we have been together for more then half a year and she has been very close with me. Yet for almost the entire time we have been together she has done things that make me feel worried for her loyalty. these things include in a descending order of how weird they are, Hanging out alone at another guys house alone in his room atleast once a month shes also really close with this guy. face timing the same guy and calling other guys more then me she also calls and face times that same guy atleast once a day. She has called me maybe 10 times in the total 7 months we have been together. She is also very touchy with like any guy she knows in public. she will hung guys randomly and kinda jump on their backs and stuff and I just let it happen tbh which makes me feel really weird. she goes to parties that have other guys at them without me and sometimes dosent invite me to said parties, like she might say to my face that I cant come
She will be more friendly with guys at our school like if shes with me she might be a little sad or grumpy but when another guy comes around she then be happy and laugh with them. and lastly she just knows a lot of guys like she texts 5 other guys on a daily basis and trys to wave to like every guy in the hall way that is the same age as her.
Im asking you guys this because typing some of these out made me feel silly and petty about it but I just want loyalty tbh. I feel weird bringing this up with her and I am worried that she will say there is nothing wrong with it or she might get mad at me or worse of all might just break up with me. Firstly do you guys thing these examples I gave are valid or just me being silly also what should I do should I confront her or just keep letting her be herself. And if you guys think I should talk to her what should I say and how should I say it.
TLDR
We’ve been together over 6 months, but her behavior with other guys makes me uncomfortable and worried about loyalty—she hangs out alone in another guy’s room regularly, FaceTimes and calls him daily (more than me), is very touchy with guys, goes to parties without inviting me, and seems happier around other guys than with me. Writing this out makes me feel petty, but I just want loyalty. I’m unsure if my concerns are valid or if I’m overreacting, and I’m scared to bring it up because she might get mad or break up with me. I’m asking whether I should talk to her, and if so, how.
