Warning: The following could be deemed as unmanly and wimpy (but I really don't care much about my interwebz street cred).
I've been single pretty much my entire life (I'm 20) so I am used to not having a significant other and being on my own, which I usually don't mind. However, on occasion a batch of loneliness just hits me and it is usually just after I have met a girl I could potentially pursue further. I don't know why this happens, it just does and can be quite annoying (I hate feeling sorry for myself, btw). Anyways, a situation occurred the other day at a party/bbq my buddy was having. A girl he knew came and I started to get along with her pretty well, flirting, laughing etc. Anyways, nothing much happened beyond that and I shook it off the next morning as a fun time and nothing more. I thought the girl was cute and fun, but I didn't really see it going anywhere. Now, a few days later, I find myself thinking about her too much for my own liking, reminding me of my own loneliness (from an significant other perspective).
The thing is I never thought much of her when I was spending time with her besides having fun. And now this wave of 'emptiness' seems to have hit me with her image attached to it. I am not sure if I really do feel something for the girl in question, or that my interaction with her is simply reminding me of my own single hood.
I am just wondering how normal this sort of 'confusion/longing'-ness is and what I can do to change it (it really is quite uncomfortable). Or whether their is a possibility that my feelings are attached to the girl exclusively (I've only just met her).
Weird thing to be inquiring about I know, but whatever.
