Well when she was staring at you, what did you do? Did you talk to her or ask her out? If you didn’t then she probably thinks you didn’t like her at time and she moved on with another guy.
I’m also an introvert by nature, with some extrovert qualities on some days if I’m lucky but I’m usually fairly shy. However, I can feel your pain about losing your mom too. It’s very hard, and I just lost mine in May so still very recent, but all I can say is that if you can try to go seek the help of a therapist. I did and it helped going through a group therapy session, being around people who are also feeling the same way you are makes you feel better. Knowing that you’re not alone in this pain helps in a way, but of course it’s still hard. However, we both have to remain strong.
As far as seeking help to increase your self esteem and be more outgoing, I think that’s awesome and nothing wrong with self improvement. However, it’s not your fault that you’re an introvert. People are just born with different personalities. I had asked my therapist why some kids are born this way, and she assured me that some kids are just born this way so not your fault. So as mentioned, trying to help yourself out is a great idea. However, also realize that it’s normal by nature.
As far as the girl goes, please share with us some more information regarding the situation the two of you once shared and how it might’ve changed. If you think there’s no hope in having a chance with her, I can say for sure just forget about her as dwelling on the would’ve should’ve’s won’t help you as my therapist also mentioned.
Ah dunno, you just said she currently has a BF, used to like you but is ignoring you now. Think about it, she’s behaving right and is a girl of integrity. If she was your GF, wouldn’t want her to steer clear of guys trying to hit on her, especially ones she was interested in before being your GF?
True as well, maybe she does want to say hi but I mean c’mon! Girls who show their boyfriends respect are HARD to come by nowadays. So this is obviously a pretty good piece of advice and common sense regarding how a good girl should act. So she’s probably just showing her man respect, which is good.
Oneitis is a bad place to be. All the energy you spend being consumed by this woman can be put to better use in finding a wonderful gal that is available.
