Boyfriend& Bestfriend

I've been with my boyfriend for two months. However about a week and a half ago my guy bestfriend told me he's been in love with me. I know im in love with him to. I love him more than my boyfriend. But I don't want to lose either of them. I kinda just want to be with my bestfriend but I don't want to lose my boyfriend. My bestfriend and I are so comfortable with one another, we gel so well, we laugh and everything is just right. He always says, "Do what makes you happy." But he makes me happy. I don't think I'm ready to lose either of them but there's no point in denying my feelings for my bestfriend. What should I do though? I'm so confused.
