long distance relationship the best?

So I am torn between living on campus next year or continuing to commute. my friends are getting an awesome on-campus apartment and I really want to live with them. However.

I have been with this guy for about 4 months and things were pretty good until he broke his leg. He became very hard to deal with and started being rude to myself and my children.

Stay or leave the relationship?
A year and 2 months together, used to live together, now staying apart due to work/ accommodation reasons. 3 years younger than me.
