Sorry I'm a bit intoxicated right now and thought you guys would understand it bet than people over on on of these relationship subreddits

Been together for a few years and were on a break for a couple weeks beginning of the year after moving to a new city, where he slept with a few girls from our now mutual extended circle of friends that meet each other at least once a month. We quickly got back together but the damage has been done. I didn't sleep or went on a date with anyone during that time though

I know he only slept with that girl once and it didn't mean anything, but it's awkward that we're all sharing a circle of friends and I have to look at her fugly face on a regular basis. I get it I'm being petty, but I also don't want to stop hanging out with them, knowing that some of them are actually pretty cool people and she's objectively way less attractive (on the verge of being obese)

I just don't know how to cope

Edit: We just got back from another of these meetings, went to a pub quiz and it was awkward to say the least. I understand that she's in an awkward position as well but having an upper hand as she's already been mates with everyone for way longer than me
