I had a huge fight with my boyfriend it was totally my fault and I've apolgised but he won't reply to my text messages or answer my calls. I'm not sure what to do should I just leave him until he's ready to talk to me or should I go to his house? I haven't been at school so I don't know what's going on :(

You stop contacting him, 100%. If he wants to contact you and accept your apology, he will. Do you really think that pestering him will make him feel better about you?
You can't undo everything in life with an apology.
You don't have a right to 'know what's going on.'

You don't have to do anything but be cool and keep your dignity and self respect after you have apologized. I doubt if it was ALL YOUR fault anyway.

You just got tired of taking his crap right?

That was harsh but true. Its just making me feel so anxious sitting waiting for him to contact me.

I didn't get a chance to apologise in person so I sent him a text do you think maybe that's why he's not responding? Would it really make it worse if I just went and seen him my mums not home later I could just pop over there. Gee@ would be so easier if he just responded even if it was to tell me to go away

The best way to apologize to someone who doesn't respond is on paper. Yep, old fashioned writing on paper, and sent through the old fashioned mail. Texting is too easy. A letter shows time and effort, and it can be read when the person wants to rather than 'in your face,' and it is intimate, personal, unlike a text.
