Do you think we will ever be best friends again?

I think you definately could be, it depends on whether either of you is willing to apologise and try and make a fresh start. I think it also depends on how old you are, I fell out all the time with my friends when I was about 13 and it never really affected our friendship. However, now I've witnessed a few of my friends having fights and then never really being the same again...I guess because we're all going to university next year they feel like there's not much point in trying to get along any more.
You sound like you care about him though, so show him that you're there for him and I'm sure things will sort themselves out.
Good luck, I know how you feel xxx

yes, just tell him you are going through some hard time at home but that you really appreciate his friendship. you guys should try talking about your problems and stay connected it would help both of you guys. but stop arguing.

It depends on what type of friend you have.
It might be cliche, but that doesnt mean that it isnt true.
If you are true friends then something like this wouldnt phase you, let it get better with time

sure.. just talk it over.. tell your friend you'd like a little breathing room so you can get your head together.. it happens all the time.. no worries.
