Is me wanting my boyfriend to go to his bed for a night and sleep apart a reason for him to kick me out of the apartment we had moved in together? We had two separate beds instead a double bed cause we both knew we needed a space time to time.

He might've just had a bad day.

Unless he is quick-tempered.

If your name is on the lease, then technically, he cannot kick you out. If you are on the lease, then you need to talk to the landlord if you want to stay and see what they can do (do they have another apartment that you can rent).

If you asked for space, and your boyfriend decides to kick you out, then you might want to examine if the relationship is worth it. That's how a child behaves if they hear something they don't like.

Personally, I think it's rediculous to be in a commited relationship and not be able to find a compromise ... But that's just me.

Had you discussed this preferrence of sleeping arrangements as a couple?... Did you come to an clear understanding or agreement that THIS was something you wanted ? Was he given the opportunity to voice his concerns about it? If not, this might very well be the beginning of your undoing.  I'm thinking he may have just simply took your preference to sleep apart offensive as it may seem (at least to him) some sort of rejection. 

Legally, if your name is on a lease, he has no legal right to kick you out .. Period.

Not in a relationship with two mature adults who respect each other.

Sounds normal love is tough
