We fight too much asked for divorce

My husband and I have been married for 3 years we’ve been constantly fighting over every little thing a couple of days ago he said he’s done removed his ring and asked me for a divorce I know he still loves me but he’s telling me all the fighting is making unhappy and he can’t handle another fight I keep apologizing for the hurt I’ve caused him with my nagging but at this point it looks like this is it what can I do? What can I say to make it better?
