What am I lacking?

Before I didn't really care about my appearance but ever since I had a crush on this guy I always end up comparing my face to other prettier girls and as a result I just feel not good enough. I made random guys rate me on Instagram to get mainly 7 or 8 out of 10 but the fact my crush doesn't like me makes me feel as if I have something lacking.

Honestly the thing with pretty women is we love them, any of you, you can be stupid, dull, downright mean and we'll still like you. But some of us guys are looking for a partner and some of us who have been in long relationships know that those looks aren't everything. Maybe what you're lacking is a compatible personality.

It's not about comparing yourself to others, it's about being courageous and going up to him to talk.

I don't believe I have bad personality I am a nice to people and sympathise for them and I quite smart (not trying to be arrogant) but I still don't get what this boy wants.

Why do you think he does not like you, I guess it is about your appearance? How is he around you, do you message him, do you see him often?

I still don't get what this boy wants.

He is shy and introverted so it is difficult to decode him he gives me mixed signals sometimes I see him staring at me. When we have a convo he is super awkward and nervous. But in the same time we have texted each other and sometimes he doesn't watch my snapchat stories. When I compliment he doesn't compliment me back.

Are your compliments direct or indirect and is it only one sided? Don't worry about Snapchat I just flick through people's stories so even if he did watch it he may not have actually paid attention. The thing is you get in what you put out, if he doesn't seem interested in you he probably isn't, but if he makes an effort to talk to you and stares at you he probably likes you a little bit at least.

the compliments are more like "I like your hair", "I like your shoes " etc

Well they're quite vague I've had girls in relationships tell me they like my hair, I wouldn't think they liked me. Try be a little more direct or compliment a specific characteristic of his. Say for example you like how nervous he seems around you and you think it's cute.

But tbh I don't want desperate or creepy
