Me (F24) and my boyfriend (M26) have been together for the past 3 years, Around 2 months ago he had just told me that his classmate from high school has passed away. As someone that has dealt with grief a lot, I could understand why this was hurting him. But recently he has a not going to work and been using the excuse that he’s grieving. I supported him for a while, but then he started using it as an excuse not to do anything (Dishes, Cooking, Clean, Shower ect..) I brought it up to him a couple days ago and he became very defensive saying that I wasn’t supporting him in his grieving. I would definitely understand if it was someone he was close to, but he hasn’t talked to this classmate in years. but I let it go. yesterday, I brought it up to him again and this caused him to have an outburst and he left to go stay with with his sister and he hasn’t came back yet. I’ve texted called him a couple times but he hasn’t answered. I just need reassurance that I’m not being toxic or anything. What should I do now?
