How to handle this situation?
So I’m 33 and live with two other male roommates around the same age. And generally have had no issues, but had a bizarre altercation yesterday with one of them. For context I generally walk around the aptm in my underwear if there are no guests around, usually because I’m just grabbing something from the kitchen. One of my roommates has asked me to wear pants more, and to an extent I have (other one could care less outside of some Walter White jokes). But I walked into the kitchen in my underwear and he was there, he said nothing but walked up behind me and no joke gave me a wedgie so bad my feet left the floor and my waistband ripped. This guy is twice my size, and he basically said he will do it again unless I wear pants around the aptm. I cursed him out and haven’t brought it up since. I’ve been wearing pants all the time now, but I feel like a pushover for not contacting our landlord. But I’m also embarrassed that happened to me as a grown man. What should I do in this situation?
