I had no clue here this thread should be, so I made it here.
So me and my (i guess ex) girlfriend are going through some tough times. She wants me to get a job at places I dont want to work (not really important to the topic, just explaining why we're having a tough time). So seeing as how I dont want to work at these places and she wants me to, shes upset about it. So, we're "officially" broken up. But heres where it kinda pisses me off and doesnt make sense. She still stays over at my place, kisses me, we have sex, and she says she still wants to be with me and stuff, she just wants me to get a job.
TL;DR: My GF and I are "officially" broken up, but still act like we're in a relationship.
Before going on, I wanna say we've been in a relationship for about 3 1/2 years, im 19, shes now 21. We've been broken up about a month or so now.
So, on the 3s she turned 21. She likes to drink, so she went to a bar at midnight for her birthday. I knew something fucking terrible was going to happen and make me feel like shit, which ended up happening. We tease around, like asking if so-and-so hit on us if we know someone of the opposite sex talked to us. We do it alot, but dont flirt back. So I asked her if anyone did at the bar. She said yeah, and I wanted to know about it, so I started asking her some questions. She wouldnt answer me. All she says is, "we're not dating, I dont need to answer to you." (i can be very jealous, so i wanted to know about this guy). So after a bit, I get some answers and she tells me shes not interested and whatnot and I believe her, though I feel like shes still hiding something from me. And just tonight, I learn that she made out with another girl at the bar. Now, I know we're not officially together, but we still act like we are. She also told me she'd WAIT for me to get a job and whatnot to get back together. I asked her about it, and after her again saying "we're not together" for quite awhile, she answers some questions. She told me she basically started it, and they made out 3 times. She didnt know that girl, a friend of hers knew her, and thats how they met. She (my ex gf) told me she (as in my ex-gf) wasnt bi, and she wants interested in her. All she said was "she found her attractive and she was drinking." All this while doing all the things people do in a relationship with me.
I feel like she cheated on me. I know we're not "officially" in a relationship, but we're still doing everything as though we still are. She told me she'd wait for me, and she said she isnt bi and isnt interested in this girl, so I wanna know why she'd do that and all she says is that she was drunk and found her attractive. I would like to know others peoples thoughts on this. To see if other people would consider it cheating/if they'd feel cheated on.
EDIT: it may also be helpful to know she was drunk when they made out.
