If you ever feel like a relationship isn't working out, PLEASE, don't just ghost and block people.
I am not talking about situations where one's safety is at risk due to psychological and/or physical abuse, of course. I know it's probably a very common thing to vent about but still - when you realize that he/she is just not the right person for you for any reason (any is valid), at least be a decent person and let them know definitively why you don't want to talk to/see them anymore before you cut ties.
I've been on a receiving end of a particularly painful example of ghosting and blocking of any contact from the person that I had almost two months of great relationship with. Which ended so abruptly without me even having a chance to respond/say sorry for whatever I did wrong. It's been 2 years and I still haven't fully recovered from that experience and it brought me so much heartache that I woundn't wish this to my sworn enemy, it really is that bad. It has severely affected my ability to actually develop feelings for people, it was a literal heartbreak where my heart as a place where feelings should flourish is just not the same whole functioning thing anymore. Thank you for listening and I hope at least one person sees this post and it helps them to not totally ruin another person's mental state thinking ghosting/blocking is ok in literally ANY situation.
