I’ve liked this one boy for quite a while and for about 4 months he’s been showing very obvoous signs that he likes me. He’d been staring at me in class often, trying to show off in gym when I was around, try to copy other guys that I was friends with, and many other things such as telling me how smart he thought I was and taking my books back to the library for me and generally doing whatever I would ask. He would beg me for gum and candy and test answers when he either had his own gum or candy or clearly knew the answers and he’d flirt with me off and on. My mom even told me herself that she saw him looking for me after school and looking at my mom’s car that was waiting to pick me up often when he walked by. And she doesn’t like this guy very much, nor does she lie.
Now normally I’d think that a guy like this was just being nice or maybe liked me a little bit but, see, the thing is that ordinarily this guy is a huge douchebag to literally almost everyone. We’re not bestest buddies or anything either, so it’s not like he’s being a really good friend or anything.
Two weeks ago I sent him a message on facebook telling him that I really liked him and to tell me what he thought about it when he got online. He got online, nothing. Nothing the next day or the day after. I told my friend about it who just happens to be a good friend of his and she asked him why he was ignoring me. He told her that he wasn’t ignoring me, he just “wasn’t sure about how to respond yet”.
“Yet”. This was two weeks ago. Riight. I was really sure he liked me and he’s so rude and brutally critical and honest that he would just tell my friend if he didn’t like me or thought I wa gross. Now he won’t talk to me at all. He hasn’t said a word to me in two weeks, yet I still catch him staring at me.
…What’s up with him’ Thanks for reading/answering
