Okay, so I'm just jealous. That's fine, but breaking up is not a solution. I'd like to actually work on this.
The photographs are understandable, especially given that they are mostly group ones, I just do not understand the ones of them kissing on the lips/cheeks in solo photos that are everywhere. I suppose it's just weird for me because I will show my friend his profile and they'll scroll one swipe and just see a ton of photos of him and his ex and it's awkward, especially after half a year. I think that's definitely insecurity.
I disagree with the second. I tried talking to them but they spoke in the third language. I told them nice to meet you and asked about them and was standing in the circle smiling when they talked and walked around trying to follow them, but they just kind of looked at me or said "Hi" and one girl who is goofy and nice to everyone came up and kissed me along with a guy who I'd met at a previous interaction. The rest just stood and past their "Hi's" they went to the third language. I spoke with my boyfriend only in their native language (not their second one that I don't understand) to try to not make them feel awkward by my foreignness, but nobody said anything more to me.
One of the people (the guy I met before) invited me to a baby shower for a couple I'd never met in my life. I politely declined because I do not know the couple and that would be rude, but said I would love to hang out with them another time and I said to pass on my congratulations. The next thing that I heard about them was recently from my SO telling me that they all invited him to his ex's birthday party...
The meeting friend thing I ended up apologizing about for ages. It just seemed a bit weird that she called him possessively like "I had the best day with MY George (fake name)." Would you like your SO to go out on a day that is important to you that you really need support with another attractive person (whom you've never met before) that takes couple photos with them and calls them "my [SO's name]"? Am I supposed to just smile and be like "that's nice!" I just felt it was a bit hurtful and disrespectful but I apologized for the way I handled it.
