Hello everyone. I am looking for a little advice, or possibly just some reassuring. I will say in advance that I am not a very trusting person, I don't trust anyone except my parents. My girlfriend and her daughter are going to Europe for two weeks soon without me. We have a few trust issues in our relationship. She has cheated on her two previous husbands, one of them with me, and we have been fighting more recently about her inability to communicate with me. She didn't even ask if I wanted to go or even listen when I brought up the idea of going on a vacation together. I am starting to think that she may be actually going with someone else because she doesn't even want me to drop her off or pick her up at the airport. She doesn't think she can call me from Europe because it is too "complicated" to call internationally. In my mind this all adds up to a big red flag. Maybe I should break up with her prior to her leaving so that I don't have to worry while she is gone and I can take the two weeks to get over her without her luring me into getting back together. What do you think? Should I just pretend like I don't care that she is going so that I don't seem insecure, should I tell her about how I feel and see what happens, or should I just dump her?
