Meaning of, "if you need me, I'm here for you."?

I have a great guy friend that's been giving some signs he likes me as more than just a "friend". He just texted me, "if you need me, I'm here for you." He's never said something in that vein before. Am I reading too much into it? Guys do you say that to all your "girl" friends or just special women in your life?
