Red flags or insecurities?
My GF(24) and I (M24) have been together for almost three years and things are going pretty well. However there are several times were I look back feel like an idiot for giving her the benefit of the doubt. There are three main things that have always stuck out to me and still bother me if I think about them. My question is am I being insecure and can't let things go or are these genuine red flags. 1- The Beginning of our relationship... a little back story we had been friends on and off for years prior to dating and had both liked each other at different times but never seem to make it work for whatever reason. We start taking again and after weeks of me giving her rides, making her dinner, slept over my place, even had a few makeout seshs. Things really felt like they were going somewhere and it seemed mutual. Then out of no where she ghosted me for a week. We went from talking frequently and seeing each other at least once or twice a week to radio silence. The reason she gave for the silence was because she was busy. Anyway 6 months after that we were talking and it turns out during that week she ghosted me she had sex with her random hookup guy. I was devastated, that whole time I felt like I was building a real connection to someone and it had all felt like a lie. And now currently when my gf brings up our first kiss I can't help but be a little insecure about it cause she had sex with someone a week after and was talking to this guy throughout the entire building our or realonships. I know its technically not cheating but definitely feels similar. 2- About 1 year ago from today her and her friends went to some resort for vacation. When she posted pictures from the trip there were three male workers who followed her and liked all her recent pictures. When I asked her about it she said they were just the friendly workers from the resort and not to get jealous. Anyway I see on her phone on day that she was DMing at least one of the workers flirting back with him. I saw a video of them dancing together in the club and text of him calling her baby and asking to see her again. My stomach dropped again. I immediately confronted her about it and she said that I was overreacting and nothing happened so it doesn't matter. I disagreed and said this definitely violates my boundaries and how this isn't cool with me. 3- Wondering eyes. Whenever we go out to the college bar and her ex boyfriend walks in she is always looking in his direction. I thought I was going crazy but it happens almost every time. And it's not just with her ex boyfriend. Last year while at our local college bar. It was one of the rare times were I was there before her. And of course the night that I am there so is her ex-fuckbuddy from the first story. She walks into the bar and gives me a hug. As were hugging her ex walks behind me and as she pulls away from the hug she gives him this look. A look that I can only describe as fuck me eyes. Jaw on the floor and smirking while looking up at him. Totally ignoring me and staring at him. Her ex continues walking and she doesn't say anything even though im standing right there watching that all unfold. I haven't said anything about this but it's lowkey eating me up. That brings me to the question of am I being insecure and crazy or should I feel valid about these particular issues. Yes there are all relatively small issues individually but when I think about them all together it makes me feel stupid and like I've been a fool this whole time. I think that I have a hard time letting this go because I can't tell if its actually nothing or something to worry about. Please looking for any advice of what you would do in my situation?
