So I’m dating this girl and we’ve been going out for a few months now which has been 100% amazing because I am absolutely head over heels for this girl, I’ve liked her for a long time and no other woman holds a spec of a candle compared in my eyes and things have been going good for the most part. We’ve gotten past the major honeymoon phase and onto the more serious and relationship building phase and it’s been going all good for the most part… however I noticed her being weird and upset a little every now and then and when I’ve asked her why she’ll say things like “I feel like you don’t like this or that about me” or “do you really like me or how I am” which is odd cuz I’ve literally never told her I didn’t like anything and am always interested in whatever it is she’s doing or her little quirks and quips, again I am absolutely MIND CONTROLLED by her but some things she does I don’t get (which is completely on me) and when she gets drunk or hangs out with this one specific friend of her she acts out of character and I don’t really like that but I don’t not like her because of it so I didn’t mention it to her besides when I tell her to focus on her and her friend so they can have fun and don’t worry about me. I have however voiced some of my concerns and things I don’t get or appreciate to one specific friend who would help me deal with them and find solutions. So one day my girlfriend comes up to me and is acting upset so I ask her whatsup and she goes on this topic about how I act differently and more distant when she drinks with this friend which she never seemed to notice before because I’ve said and done the same things to her when she does which is to do yalls thang, I did however tell this one specific friend that i didn’t get or appreciate it that much which I thought was weird but didn’t pay it any mind until over the weeks stuff like that would happen more and more often. So this next part might need some background so here it is… before I got with the girl I’m with now I hooked up with and was FWB with a girl I met at a party(I’ll call party girl “R”) it went on for a few weeks and then ended about a month before I started talking with my current GF it ended fine no hard feelings or attachments just a clean cool mature break no feelings for each other but I also never told a single friend of mine about “R” at all ever . “R” didn’t go to the college I went to at the time so I never thought I’d see her again in person and didn’t for the months I was going through all this but one day I see her on campus and go say hi and ask what she’s doing there and she said she applied and paid to get in, I said it was nice to see her she reciprocated, that was it, end of convo and never talked to her again. That leads into this last part so back to the main story. So at this point I’m pretty sure my friend and GF are talking behind my back about me and stuff I say in confidence to them in private conversations, so invite my friend over that weekend with a plan in mind to tell him that I saw R, talked to her, and explain some of the back story then see what happens. He comes to my house we hangout, play video games, smoke🥬, eat, and then talk and I tell him about her and the background of us. The next day GF is being distant and not responding as fast or lively as usual so I’m 99% sure they talked at this point and it’s proven that Monday. I get to school, look for my GF, start talking to her and giving her hugs and whatnot but she’s being weird and not receptive or respondent. I ask her what’s wrong and she asks my why I never told her about that girl(R). I stare her blank in the eyes and said “I knew it” and start to walk away to find my “friend”. She’s following after me asking what I mean and what I’m talking about but I refuse to respond. I find the “friend” and tapped him pretty hard on the shoulder and asked “what the #UCK dude and I explain my whole plan and what made me feel the need to do so. It turns into a whole screaming match 2v1 of them allying saying they have no idea what I’m talking about and me giving explicit detailed info about why I knew they were lying and how. After that she starts criticizing me for not trusting her and “why would you even do something like that and setting me up that’s weird”.I walk away, block the “friend” and turned my phone on Do not Disturb so my girls calls or texts don’t show or go through till I calm down. I haven’t talked to her for 2 days now and don’t even know what to say, I feel upset, betrayed, and just don’t know what to think because it could mean so much more. Like what else are they talking about, are they seeing each other, and a whole bunch more stuff that is really frustrating and killing me to think about. Idk man

TLDR: A friend told my current gf about a fling I had before her that I only told him about to prove they were talking about me behind my back and I haven’t spoken to either of them for 2 days.
