Me (26M) and my girlfriend (25) have been together for 8 and a half years. At the beginning of this year I started to work as a bartender in a new place and that‘s where I met, let‘s call her K (25). We started working together about a month in and we immediately hit it off, laughing the entire time and getting to know each other pretty quickly. We talked a lot and about very personal, deep topics, often until sunrise (our work closes at 2 am). Since i started working here it was always clear she would quit in September, as she is now starting to work the work she studied for.
As we grew closer so very quickly, I was kind of careful what this gew into, talking with my friends about how to notice if you‘re developing a crush or if this is just going to be a really good friend. I was cautios at first, but after a few more talks and a short vacation joined by both our partners I was sure my feelings were purely platonic and that I had found a friend for life.
A few weeks after our trip, about three weeks ago we were working Friday/Saturday and it got kinda out of hand. On friday both our partners visited us working, which led to us having lots and lots of shots. Afterwards we went for after-work drinks and apparently K and me got pretty annoying with each other, which led to her boyfriend storming off without a word and leaving us early. My girlfriend didn‘t say anything, but the next day it was pretty clear we got on both their nerves.
Starting our shift on saturday maybe still drunk and a little hungover, we started doing shots again. The shift was fun as always, we both got pretty drunk and, in hindsight, pretty touchy for two people in relationships.
After closing however, we had one of those moments, where two people are really close to each other and both know, a kiss is about to happen. This came to a shock to us both, we backed off and agreed, that we needed to talk after we had finished cleaning.
If that would‘ve been it, we probably could‘ve talked it out, but while cleaning we had about 5-10 more of these moments, initiated by her or me, kinda like teasing the other to just finally go through with it. After finishing cleaning we went outside and sat on a bench nearby to talk it out, but we just kept teasing each other by almost kissing and other things, which in our minds at the time weren‘t crossing any relationship-boundaries, but getting as close as possible to it.
After some time my girlfriend came looking for me, as I hadn‘t answered her texts for a while, and that was when we both realized what atrocious thing we have been doing for the last few hours. We both instantly agreed to tell our partners everything, which we did the same night and the days after.
Both our partners were understandably very unhappy, but each of them agreed to forgive us for now, as not that much had really happened I guess. As I mentioned, August was her last month working here and we only had one more shift and a teammeeting scheduled together, so we agreed to just get this behind us and then never see each other again, for the sake of our relationships. This hurt us both extremely, as we were really good friends, and ending this friendship meant we both had no one to really talk about what happened and how we feel right now.
As you can imagine, the last weeks were really tough to go through, I started going to therapy and she contacted her old therapist as well. We have seen each other on a few occasions, which was pretty painful every time.
There‘s also one last thing that happened, she had her last shift yesterday and I was there, as we had a all-hands-meeting directly before. I originally planned to only come for the meeting and leave right after, but we had a new member of staff introducing them at this meeting, so I stayed for one drink after to get to know him a little bit. After the first drink the new colleague left, but when asked if I wanted to get another one by K I just couldn’t say no. I talked to her and proclaimed I would only stay if it‘s totally okay for her, and she poured me another one. We both agreed to celebrate her last shift as coworkers and nothing more. I then helped her out during the shift, so she could talk to her favorite guests and drink without having to do all the work. I naively even stayed until after closing, where she told me after all we went through the last few weeks she still wanted to kiss me. She also tried to kiss me, and had it not been for our agreement, I would have kissed her as well. But I didn‘t, and that was the last time I have seen her. I feel terrible, even more than before yesterday. I may have ruined her relationship once again, but this time it was totally my fault, as I should‘ve just left earlier, but was too naive to do so.
Just trying to get this off my chest somehow, as the two persons I would normally talk to about stuff that I deal with are both not an option anymore. Me and my girlfriend are still together, but it has been tough.
