He broke it off because of a joke

I have been engaged for about a year and last night while redecorating the house, he broke it off and broke up with me because of a joke.. he told me the other day he felt like we act like roommates. So I made a joke to his friend saying “have you meet my new roommate” and he said it was throwing his feelings in his face and ended it. I said it because it was my way of dealing with what he said and coming to terms with the problem in our relationship. I had to pack all my stuff and move back in with my parents. I’m heart broken and destroyed. I knew we were having some problems in the relationship, (losing the spark from the honeymoon phase) but I never thought he would just ended it because of a joke. He has made so many shitty jokes to me and I would get upset and he would call me sensitive and I would say sorry and forget it. I don’t know what to do without him. Seeing him everyday to him barley looking at me as I packed my stuff and balling my eyes out. I know break ups are hard but I really thought we were going to be together forever because he proposed to me and we lived together. I’m so gullible and naïve to think I would ever have my forever soulmate. ladies do you have any tips on how to get over a broken proposal and living together. I keep crying on and off and just want to be held by him.

Edit: I love the fact people love to judge other people’s relationships based on one short post and say they would of dumped me to/ I probably was the reason the relationship was toxic. Great support. Great way to help someone who is destroyed by this. I hope none the ones who jump to conclusions have your fiancé leave you and you feel how I feel and get bashed.
