Crazy to want this, even for awhile...

Is it possible to be happy and still want to cry every time I hang up the phone? Is it crazy to think that I'm in love when getting out of the car breaks my heart? Or is it more likely? Does it make sense that I want to be with him so badly that it hurts to say goodnight? Am I just crazy clingy and that's why this never works out? Am I overstepping a boundary to want to see him more than one a week? It is good for us, and he is right. Infatuation is wanting everything right now, love is thinking long-term. Only seeing him once a week keeps me excited and interested, and only spending the night with him maybe once every 3 weeks makes me cherish being in his arms. Is that what makes me think I'm in love? My mind tells me I'm infatuated. My logical self tells me we've only been together for 3 months and we haven't spent nearly enough time together for me to truly love him. My heart tells me differently. I look at him and feel that warmth in my chest. He holds me and I close my eyes and melt. I see his name on my caller ID and my heart speeds up.
Vulnerability has always fascinated me. I feel far too vulnerable to tell him how I feel. I know he doesn't feel it. I know he wants to someday, just like someday I want to share my life with him, but at the moment, it's not there. Do I have the strength to tell him how much I care about him, knowing he can't truthfully say it back? I am strong enough. I have to be, because I do this to myself.

It was like shooting a sitting duck
A little small talk, a smile and baby I was stuck
I still don't know what you've done with me
A grown-up woman should never fall so easily
I feel a kind of fear
When I don't have you near
Unsatisfied
I skip my pride
I beg you dear
Don't go wasting your emotion
Lay all your love on me
