My boyfriend competes with me, what do I do ??!!?

That is pretty weird. Mostly because he's a male. Tell him he doesn't have to be so competitive, and it's hard to be his girlfriend if he acts that way. Tell him to cut it if it bothers you. Just ignore him after a while and he'll probably get the hint. Or you can just act normal and pretend nothing happend, either way he'll never be better than you at whatever your doing because he's only copying you.
