End my relationship?

My boyfriend and I have been dating for four years. Four months ago we were both offered jobs by a foreign employer and moved to another country and started living together. Before moving abroad he had suggested that we get married but I wanted to try living with him before making any decision. But we have not been getting along since we moved in together. we are fighting over trivial things all the time and each time we argue we do not talk to each other for several days. And since our last fight about the dress I was wearing he has been sleeping on the couch. I think maybe it's for the best that I break up with him but this is really hard for me first because we are coworkers and I have to see him and work with him every day. The other problem is that I do not know anyone in this country and I feel alone to the extend that I'm afraid of even thinking about leaving him. Please help

Stay with him and the best thing you could do right now is say your sorry and apologize even if it wasn't your fault. You need him there with you. You also need to start communicating better & when a fight breaks out just back down and say I'm sorry nice and calmly and fix the mistake
