Legal Separation. Please help

So I have been married to my husband for 2 years but we have been together for a total of 4 years. We was great before we got married and was great the first year. But this 2nd year just seems like we lost connection. Hes not the one who will talk about his emotions. We have been fighting alot lately over the stupidest things like this morning was Snapchat! When he goes and hangs out with his brother and/or dad he completely shuts me out. He comes home and plays on his xbox for hours even when Im home. At this point I dont know what to do. We have a apartment the lease is up on Jan 31st. I talked to my gma and gpa. They said I couls move back home.
