Don’t like my gf best friend

First read the whole thing before you come at me.

So my gf has a friend she knew long before me. I’m fine with that. I don’t like when they hang out because I’m a insecure little bitch so. When we started dating it was ok but now they spend all there time together. She won’t even tell me till there already hanging out and I want to tell her to stop hanging out with her. I’m not going to I just want to. I’m not the person to say stop doing this. I just deal with it like I deal with the other stuff. And I moved away last year so we have a long distance relationship. I see her about ever few months. But recently her friend come out as queer so now I’m even or like “please stay away” not to her and everything. And again I’m a sensitive little bitch and didn’t like when my gf would wear her swim suit. It most likely because I’m fat and hate my body and she wore a bikini so I bought her a new one.. like when we saw each other last I took her to the store and let her pic a bunch to try one that was a one pace and I bought one for her that wasn’t so revealing and she went on a boat with their friends today. Didn’t tell me till after she was there and sent me a pic to show me why she wasn’t texting and she was wearing here old bikini. There a few reasons why I got her a new one. Her old one was super tight because she’s had it for 6 years so it was like super tight showed everything and I hate myself so I guess I take it out on hero. I don’t mean to but still. I just don’t like her friend I want her to stop hanging out with her but I don’t want to tell her because it’s still her friend and I can’t make her it’s just my stupid feeling. As well as I don’t want to tell her because when she told me to stop hanging out with my best friend (I did I stoped talking to her) but anyway I was upset when she made me do that and I don’t want to make her upset and. I hate myself for wanting to make her stop hanging out with her friend I’m just being jealous and shit. Sorry for the rant. Also sorry for any error I’m to lazy and tired of myself rn to re-read it

And like I said I want her to stop not going to make her like she made me.
