So my girlfriend is going to Vegas for 4 days 3 nights for a work thing. People from all over the country are going to be there and high ups in the company go. There is meet and greets and she says she's looking forward to "networking" so she can advance her career. Because of the time zone difference I'm not even going to be able to talk to her before she goes to bed. I am a wreck over this as my girlfriend is very pretty and loves being the center of attention. She has never cheated before that I know of but I am worried. I thought about it a lot and I don't think I want to be in a relationship with someone that is going to Vegas without me, and then she has another work trip in a couple of months to Minnesota which is every year. I haven't talked to her in 5 days and am seriously considering just breaking up..am I overreacting or am I justified in breaking up with her?
