To fix a broken friendship, communication is your number one priority. You need to talk to the person and tell them how you feel and why you feel that way. If you are the person to blame, then you should genuinely apologise. But, if the other person is to blame, don't demand an apology and don't blame them for everything. I'm sure it's a simple misunderstanding between you two and you'll resolve it pretty soon. If you need anyone to talk to, we're all here for you :)
