love or not?

I'm lost in my thoughts tonight. I'm not sure which way they are going. Everything is kind of running around in my head and bumping into each other. Started a new job. Not much. Just a little diner job, working 3 shifts a week and maybe an extra here and there if they call me for a cover. Haven't had much time to sit and put my thoughts down and get them out there.
Has anyone ever asked you if you believe in love at first sight? I've been asked before. I said no. I do not believe in love and first sight. I believe in a connection between two people that can end there or turn into a deep caring of each other and then love. You go through the "omg are you serious?" "I like that too" and the "wow we have a lot in common". I've been through it a million times. And they never went anywhere. I thought I was in love. WRONG!
Now I'm head over heels for a man that I didn't have those with. There were a few hey I like that too here and there. I'm wondering though... a question that always sits in my head and I never spit out. Can that real love that you feel... the butterflies and the sweaty hands and jitters and the giddiness, does it last or die? I don't want it to die. I want to feel this for a very long time. I don't want to let go of the feeling of being safe with who I love. The man I spend my time with is amazing. I don't plan on letting go of him at all. But can you fall out of love with someone as quickly as you feel in love with them? I know people have told me before that they just didnt love me anymore. but it is possible when you have everything going so good.
I know that the distance between two people is always a good thing. You need to have your space or youll go nuts being with them all the time. And I'm not with him all the time. once or twice a week is all i get b/c of work schedules and I don't want him to get sick of me. I guess i'm just being a worry wort again.
More thoughts for you ponder over.
