Hey there, let's start with a little background.

My partner met this girl about a year ago right here on Reddit. At first, they were just friendly and she claimed that she was a lesbian ( turns out that's not the case) and that she was dating a girl long distance. Partner initially presented this as just a simple friendship. I'm sure you can guess, that it turns out it wasn't. My partner didn't fess up to anything until after just feeling that something was up ( lack of affection/sex and generally treating me like I was a piece of furniture ), I snooped…. I know this was bad but I felt like I was going crazy because what I was observing wasn't adding up to what I was being told. We had a big blowout over it but I thought we had come to an agreement.

Well, of course, they continued on as usual without me being aware until around this July when I started getting the same feeling that I did before….shocker.

So, I believe, I have plenty of reason to dislike this chick. I don't feel this way about any of the other girls he talks to because he's always been upfront about them. Beyond the obvious, this girl is: A) always texting him- seriously, we can't do ANYTHING without her texting. This includes us driving to my parent's hotel so my partner could meet them for the first time. She seems to have no life outside my partner. B) saying inappropriate things to my partner while she knew I could hear. This to me just seems rude and disrespectful. C) I'm strongly convinced she cheated on her gf with my partner and I'm further convinced she left her gf for him. I simply don't want anything to do with cheaters. D) I also believe that she was trying to manipulate me to doing stuff with the two of them, not because she was interested in me but because she knew my partner would like it which made me feel used and gross.

Sorry this turned out to be vent but I guess my question would be how to navigate all of this as she is supposed to visit in Feb.
