<human>: So, I've basically been in long-term relationships since I was 14. I dated my high school sweetheart for 4 years. Dated a guy from the time I was 18 until I was 21. Then dated another guy from the time I was 21 until about 2 months ago. This is the first time I've truly been "single", and I actually am enjoying it! I'm loving being able to work on myself, focus on what I want, and not have to worry about anyone else. It's lovely.

Now onto the dating thing. I'm sort of seeing a guy I know, VERY casually. We've gone out for drinks a couple times, gone out with mutual friends, and gone to lunch once. We text a lot and are making plans together often. He's very attractive, nice, educated, and genuine. But for some reason, I'm having a hard time feeling that "spark". Maybe it's because I don't know him very well yet. But I can't help but think it's actually because of something to do with me. 

Since I was 18 years old, I've only dated 2 men. TWO! And they were both very serious, long-term relationships. For so long I have seen other guys as strictly platonic. Maybe it's because I'm newly single, but why am I not feeling that "butterflies in my stomach" feeling for other men? Is this going to last forever? I hope that someday I can feel giddy over a guy again.

I don't know what my question is. I guess I'm looking for input into my situation. Also, should I keep going out with this guy casually and just see where it goes? I do enjoy hanging out with him. Thanks for reading!

Could you distill the essence of the text into 1-3 sentences?
<bot>: I've been in serious relationships for so long that I'm having a hard time getting feelings for anyone else. Dating feels weird. Is this temporary?
