...your house PHONE # (land line), I misunderstood.
Okay, but "TOO attached" early and clingy overwhelms people, slow down, become friends first. You scared him into forgetting. Be confident in yourself, but not overbearing and don't take away his "lead", he has to feel relaxed with you, not go into shock whenever you're around.
When you dance, let him lead, don't grab him and throw him onto the dance floor. Don't squeeze him into your schedule with a deadline. People (friends, strangers, etc.) sense when you want to "attach" and you are eager (your eyes light up, yes, people notice this) and understand that you "EXPECT of them" (have high expectations of them) immediately and realize that they either can't "measure up", or that they can use you. Either way, be careful of being too eager.
