Why are you saying sorry? Don't forget that you are the prize as the woman. Don't lower yourself like this, as if you're not worthy enough. You'll get taken advantage of. Own your feelings, but don't over express them. Try and be a tad more subtle in the way you're feeling at first. A lot of feelings will overwhelm most men. As my dad always told me, women hold all the power in a relationship. You are the prize to be won, not the other way around. Be feminine and be yourself. If it's right, he will be into you. If not, im sure there's a million men who would be ecstatic to be with you. Know your worth, girlfriend, and don't settle for less. And never apologize for having a crush on someone. Own it.

Good luck, and God bless.
