Being overly available will cause his level of interest in you to drop. Because you are always there for him, he may start taking you for granted.

Wanting more attention from someone you are attracted to is natural. Expressing it when you don't know how the other person feels about you is tricky. Asking for too much, too soon, can make you look needy and demanding.

If the feelings of attraction are mutual, then it will happen, but only at a pace that is comfortable for both parties. Enjoy each other, but allow things to move along naturally.
