Hun, I was in an abusive, complete $hit relo for 4 years and I'm not saying what I'm saying is the case but he sounds like he is manipulating you by saying that it's over!
He's trying to control you, control eventually leads to abuse whether it's verbally or physically.
Relationships end all the time and it's usually for the best, don't worry about the house, it will get sorted.
In my opinion you should leave before it gets really hard to get out, I'm really sorry if I'm making it over dramatic but I've been there and don't want you to get there.
No matter what his issues may be he should never make you feel guilty, he should be able to talk it out and help you understand what's going on and the reasons why he's being acting nasty.
You could also try talking it out which I personally wouldn't do, but whatever decision you take, if he really loves you and wants you he will come chasing and begging for you.
Relationships start off sugar coated, but things get in the way, people change, their true colours come out but that's when you take it as a lesson and continue the journey to finding your ideal other half.
So whatever you decide to do be strong and do what makes you happy and never ignore your gut feeling because it's always right
