Might've posted something similar here before, but it's always nice to vent and chat to people outside my friend group about stuff!!
I'm looking forward to seeing my friends again after so long, which is happening soon as I'm finally heading back to my uni city to see them and to start (some) in-person classes again!! I've felt so much FOMO over the last few days as they've all been hanging out together, and I'm desperate to see them - especially as I spent my pre-COVID year largely isolated anyway, due to social anxiety and other dumb personal stuff that prevented me from going out much.
Unfortunately, my ex is a large figure in every friend group bar one, and is at every event. I no longer have sexual or romantic feelings for him (debatable whether I had them to begin with, hello discovering my sexuality!!) but I cannot stand to be around him. I don't know what it is specifically, but he genuinely makes me feel uneasy and uncomfortable.
He wasn't abusive, but he was emotionally unavailable and I the opposite, which resulted in a lot of messiness and bad feelings on either side. He revealed to me that he used people and only cared about himself, and even though he might've been exaggerating it's stuck with me even now. I was quite young (18, he 22) when we got together, and very naive, so I clung to him even though he was at best ambivalent to my personality, body and general presence in his life. He's changed his entire look multiple times since then, and has even started doing things (drinking, doing drugs) that he was previously vocally against - to the extent of accusing me of having drinking problems because I passed out once at a party (for context, I drank about once a month at most back then, and not at all now). It seems so fake to me, especially as he's started dressing and acting exactly like my best friend.
I guess I just connect him to all of the bad thoughts and feelings I had around that time, as well as to a side of me I'm really embarrassed about (I did a lot of stupid things and was an absolute mess at the end of it all - I know that's relatively normal for first relationships but I'm very sensitive to cringe-worthy behaviour...). I'm probably projecting a lot and should learn to get used to his presence because it's likely it'll never go away, but I feel as if he's malicious for some reason. He was always one of those people who take their energy from others - not in an extrovert sense, but in the sense that he physically needs to be the centre of attention in a group, and often forces himself to completely blend in (ie becoming goth in a 'goth' group even though he hated that type of fashion before) so they'll accept him. He doesn't seem to realise that it's personality, and not looks, that get you important personal connections. Admittedly I have a strong fear of abandonment after a lot of my friend groups and family members drifted away in childhood/adolescence, so I'm always worried that they'll go off with him instead and that he'll treat them badly as he did to me.
Anyway, sorry for the long post - it's probably quite difficult to read... but I guess I feel as if my ex is still the same old guy he used to be, and that so many people like him now that he'll never change. It's like he's getting a neverending source of external validation, and I feel nervous about what's going to happen to my friends if that ever stops coming. I can't go in there and break up friendships just because a guy insulted me a few years ago, nor can I even tell those friends about my history and reveal his track record with women (it's kinda dodgy) - he might actually have changed, and I'd seem like a clingy, possessive, bitter woman who's letting her own problems interfere with other peoples' happiness. If anyone has any advice, I'd love to hear it!! <3
