Search Results: up front with men

Okay so I’ve been dating my girlfriend for about 2 months now and I really like her but there’s one issue, she recently went to a Country Music Festival far from where we live (as we both live kinda close) but the issue is before she left she seemed distant (she wouldn’t acknowledge my mother, sister or family), she ignored my calls the night before leaving before leaving so I thought something was up, then I asked last second if I could go and she said no (even though her friend brought her boyfriend as her her sister and friend all went as a group), she ghosted me for the weekend, I asked if she could face time or send snaps late at night (she refused every night), one night she called me crying about how lonely she felt on the trip and then a guys voice came into the background and she hung up the phone immediately, the next day I called her and she swore she was climbing a hill at the camp while on the conversation but it sounded exactly like her mown (and the duration she usually mowns for before she orgasms) but yesterday I asked her if she did anything with anyone and she completely denied it (though she’s very smart and probably knew to say that as she majors in psychology) I had faith until the next day I asked her high if she ever had sex in front of someone else and she said yes, beside 2 men in a guys camper, she then weirdly sighed after saying and even tested up a bit and this raised major concerns for me because she had told me on numerous occasions that she had never had sex anywhere but in houses, she had lost her virginity not even a year ago and hasn’t been camping since that, not to mention the fact we live in a place where it would only had been possible to camp within the last three months, she’s sworn she’s never had sex out of the city we live in and if it where a parked camper in the city why would there be 3 guys staying in the camper? I for sure don’t trust her anymore but do you think she cheated on me, if she did what should I do?
