I had something very similar to this happen to me. Me and my Ex were pretty much inseparable, we had been going out for 2 years and literally saw eachother every other day. So anyway, I didn't like hanging with my friends and my girl at the same time since I was a strong advocate of dividing time between chilling with friends and time alone with my Girlfriend. Then one night I had arranged to go to a friend's party and as I was telling my Girlfriend about this arrangement she asked if she could join. I thought why not? Maybe it would be a good thing to introduce my friends and Girlfriend to eachother.
We arrived to the party at around 9-10, but as I was not used to chilling with my friends and Girlfriend at the same time, I had opted to spend most of my evening just talking and drinking with my Girlfriend on the couch. A couple of hours later some guy who was a friend of a friend sat down next to my Girlfriend and introduced himself to us before conversing with my Girlfriend about life in general. I sit there for 10 minutes and listen, I then tell my Girlfriend that I'm going to go speak to my friends and I'd be back soon; she completley ignored me, but it wasn't really a big deal. Anyway, I return around half an hour later and they're still in deep conversation, I sit back down next to her and she doesn't even acknowledge that I have returned. A couple of minutes later to my utter astonishment, out of the corner of my eyes I see them kissing eachother. I didn't really know what to do so I just sat there for 5 more minutes whilst they carried on sticking their tongues down eachother's throats. Friends even passed by me and asked questions like "Dude, why is he getting with your Girlfriend?", "Are you not going to say anything?". I told them I don't have a clue what is going on, until finally I had enough and decided to grab her hand and tell her that we were leaving. She just carelessly pulled her hand away and placed it on his cheek, at that point I knew it was over and decided to go home by myself.
The next day she called me and asked why I had left the party lol. Needless to say I told her we were finished.
Because there's a single tendon os in my groin that hurts when I squat on the reg
But ok ok point taken, pricks
Maybe you just need to learn how to squat. Try some goblet squats with a kettlebell or dumbbell right up against your chest. If the pain persists, we'll need to progress to soft tissue and mobility work.
