how to..

...fall back. He's very busy with college work and I want to be there for him without annoying him, either just texting or in the conversations we have where I've been being very dramatic and overbearing (more so recently because I'm having trouble with not seeing him as often)...I can feel him pulling away a little.

What is the best way to get him to:

A) Miss me/think about me in a good way
B) Get him to want to call me/see me

and What can I say to:

A) Appear cool, relaxed, supportive, fun, involved in my own life but he's still a part of mine
B) Keep me on his mind (in a good way)

If your only response is "You can't make him do anything" please don't bother replying...only actual tried and true advice/real situational experience wanted...Thanks so much!!! :)
