Like swallowing nut...or washing the skid marks out of your drawers...or cleaning up behind a grown ass man...
But even beyond that I had an ex tell me he didn't realize he was on the verge of depression until he met me. Because prior to us getting together, he would spend 24/7 in his one bedroom apartment, only leave to go to work and come back. Blinds closed, old take-out boxes and dirty carpet, crumbs of soap, mattress and a box spring with no headboard or fitted sheets, mold in the bathroom, socks with holes in em, rings around the tub, nothing in the fridge and the only people he talked to were on PSN.
I tried it with him for a while and that shyt made ME depressed. When you start drinking liquor just to tolerate somebody...hell them trips to Walmart felt like freedom.
Initially I would ask him to come with me b/c I'm used to a wide circle of friends. I'm used to people just popping by my apartment for Ghibli Studio marathons and dinner. I'm used to pub crawling and board games with friends at 3am on a Saturday night in bars. Karaoke, figuring out answers to life's problems, debates in 24 hour French bakeries, traveling, brunch with professors all kinds of shyt b/c my brain can't stay still for too long and I'm a gamer too, but doing that shyt every single day non-stop?!
But he had a way of not wanting to go anywhere with me, but also not wanting ME to go anywhere either. It's hard to describe feeling emotionally manipulated into cutting off parts of urself for somebody else b/c you feel sorry for them or b/c you don't want to leave them behind.
Sometimes if these chicks are in the same boat as me, we just wanna get out the damn house. I remember cancelling a pub crawl with my friends for New Years for this dude and literally spent the night drunk on a ratty ass couch watching Robot Chicken miserable b/c he didn't wanna go anywhere.

l literally had friends and family telling me I glowed when we broke up. shyt affected me mentally and physically.
Never again.
