So it’s some complicated backstory, and everyone is non-binary. I (22) was with my ex (22) for almost 3.5 years, 2ish years in we both started dating a friend of mine we’ll call G (22/23 now (birthday is tomorrow))who id known for 10/11 years at that point.

a few months later, the friend broke up with us both. a few months after that (august ish 2023), they moved into our flats second bedroom. i started noticing some odd behaviours from them both about a week after they moved in, when questioned on if they were dating again they said along the lines of “oh yeah, guess we didn’t tell you”. originally i let it go, but after everything else it’s been plaguing me.

we skip to march of this year, and my original partner breaks up with both of us after G basically gave an ultimatum of ‘them or me’. reasons included that they “didn’t want to choose between us” and they “wanted to be single for a while”. they go to their dad’s house for two weeks. during this two weeks, G said they wanted to just move on.

i think we can all guess what happened next, but once ex came back i noticed the same odd behaviours from before! This time including “oh G just comes into my bed in the morning sometimes instead of going back to their room”, when i’d walked in on them both in bed together (on the sofa bed that i paid for). I didn’t get confirmation for about a month, when i again had to ask. after the confirmation, i was completely iced out overnight.

The sudden icing had me relying on some unhealthy coping mechanisms, and i landed myself in a&e overnight. i was already trying to get therapy (NHS wait lists are awful atm), and it has been fast tracked. I’ve been stressed to the point of no longer feeling physical pain and i’m terrified of how much damage i’ve done (i’m disabled and chronically ill).

G wrote me a note that said they “never lied” but were “sorry for not being truthful”, which mostly just made me wonder how stupid they think i am (combined with the above excuse).

it’s now been just over two weeks, am i overreacting for feeling hurt and betrayed by their choices? specifically all the lies
