Don't allow yourself to get overwhelmed with all of this at once and let it get you too down. I know it is easy to say but hard to do. I don't know how old you are, but one of the things I have learned in my forty plus years is things always LOOK worse than they are. Can you stay at your friends for a few days, just to give yourself time to replan your life?
As much as it hurts your BF is probably doing you a favor, it doesn't seem like it now maybe, eventually you will see; what is so devastating today, will seem small later in life. Don't know what the source of your arguments are, but I do know the arguing will not go away on it's own. My teenage son and his GF are always fighting/arguing, and I tell him this is not the way love is supposed to be.
Look at this as an opportunity. Try to turn a very sad thing into something that is good for you. Use this time to reevaluate YOUR life and the direction you want it to take. Don't make decisions about what you are going to do too quickly, take time to think things through. Good Luck
