I called my high school girlfriend just to wish her for the new year.. I felt so silly afterwards and I guess it was just for the reason stated by you.
If I don't feel like the person feels the same for me I tend to back off pretty quick. I'm very guarded with my feelings.
its okay MissGaga i know that u miss me so no problem u can check on me when ever u want :P loll
Oh, yes. Missing them means you care and if they don't reciprocate, that is unfortunate, but you still care. I think it is natural, my friend!
