On one hand I can see that you don’t know this person, but on the other how psychotic do you have to be to want to tape your fridge shut to catch him in the act of being fucking hungry?

This doesn’t belong here, this belongs in AITA, and yes. Yes you are the asshole. You probably don’t know him because other family members warned him about your psychotic mannerisms.

Not a lot of people grasp this concept. On the other side of the spectrum of course you should be able to vent and seek advice, but as stated resolution isn’t always within the advice obtained. I can’t say how many times Ive heard friends make snarky comments about past issues when their friends decide to tie the knot. Or do anything together really. There are people out there that all they know of your relationship is what you’ve vented. They don’t know the intimate moments spent trying to mend an argument or disagreement. During your best moments it will always be “but he/she did this or that happened”

It’s always best to try to resolve issues internally and not risk having a vulture picking at every bump your relationship may hit. For some it’s jealousy for others it’s what gets them off and you’d be surprised how common that sinister trait is.
