Very relatable yet very brave to talk to the „local pub“ about such a private matter.

I have circles I discuss such matters with:

1. wife, closest friends, therapist - matters that make me feel very triggered because they know how to get me down
2. friends, closed or niche chat rooms to talk about my stuff in general. Often not with clearname but still somewhat private matters
3. open spaces (lemmy, reddit, forums). Stuff that does not trigger me so as to not spiral out of control if a troll finds me there

Coming to the problem:

Having someone put in the last word and blocking you is actually very petty and a last resort if someone got triggered themselves. I‘d say it is dumb but I have to say I did so myself if someone was very rude.

Try to think of it like this:

• this person does not know you so their judgement does not concern you
• if they said mean things and blocked they‘re probably very young and didn’t know how to help themselves
• thinking in winning and losing is not helpful at all. You should instead try to learn and help others to learn. Its not important who has done „better“ in a discussion

Btw getting triggered normally is evidence that something has hurt you in the past and not the current interaction is hurting you but it reminded you of a situation where you were hurt. You can try to solve it by speaking about these things with your therapist or close/reflected friends.

I hope this is helpful. I wish you good luck.
