My boyfriend broke up with me after 2 years, What am I meant to do?

Forget him and move on, you were far to young too be in a long term relationship as was he, which he has now realised, you should have been out and about with your mates enjoying life, instead you have wasted 2 years of it for nothing and no he won't come back because he has probably already got somebody else lined up to take your place.
