So I've just graduated from Uni and for the final year this was this girl on my course who I liked a lot. Only problem was she had a boyfriend. Initially when she joined she was giving the standard signs that she was interested so obviously I wanted to get to know her. As I got know her better, I really started to like her and then someone else dropped the bomb that she had a boyfriend when I was talking to them about her. As I'm not the kind of person to try and break up a relationship for my own gains, I just stuck to being friends with her. However, after graduating I've suddenly got the feeling that I maybe should have done more. As I have her number, I text her a few times. I just made up some fake story that I needed help with something. We text back and forth and just had chat. She asked me to help her with something she's trying to sort out and I went to look for the thing she needed on the internet. I was doing this as a friend really but obviously I do like her as well.
After sending the information through a text, about 3 days ago, she has yet to respond. I can't understand why she's just chose to ignore it. Initially she responded in a few hours or so or instantly at times. She's been online on whatsapp a few times and read the messages but she's just ignored them. Obviously a part of me is annoyed as I thought she had some kind of interest in being friendly but also it's a simple fact of poor manners. This isn't a huge problem as some people are busy/unintentionally forget (I've done it a lot myself). However, after the year at Uni with her, I thought we liked each other and were at least friends but maybe not. I'm beginning to wonder whether I read the signs she gave wrongly but the fact that the first few days I saw her looking over regularly, laughing at unfunny jokes, always turning to listen when I spoke etc. are strange signs to give to someone who you don't find attractive.
I had wondered if she was having problems with her boyfriend as he didn't go to her graduation as she said there was no point in him coming and she originally planned on going overseas with him, but that is now suddenly off.
Any ideas of what I should do? Should I just forget about it?
Thanks
