Conflicted

So a few days ago I left my boyfriend's house because the relationship has been on awful grounds.

Now I moved into my friend's house and it's been killing me to go back to his house.. back home. Like something inside of me is aching and telling me to go back.

We didn't have any closure, any goodbye.

What should I do? My friends will be very mad and disappointed in me if I go back. I'm just tired of crying. Advice?
