Search Results: dating someone overweight

Well for 23 years, I've never dated nor have ever been asked by someone to date me, it's pretty upsetting especially that I have tried to get close to some guys whom I liked but they wind up pushing me away. My problem is I think I'm too nice sometimes, I care a lot about I like, but I'm horrible at social interactions. Like I seriously freeze when facing new people, I thought I have a social phobia but I also seem to attract very awkward situations. Anyway once someone gets to know me, they actually start liking me a lot, which makes me happy, but then they suddenly disappear, the second they say they like me or I feel like they started liking me they disappear, and this happened A LOT.
Anyway I blamed my weight for it, since my mom keeps saying that since I'm overweight, that pushes men away, but I don't want to be with a person who liked me because I happen to satisfy his weight preferences for the girl he wants or how she looks like.
What also sucks, that my friends who ask me for dating advice, they take my advice through and it works like heaven for them, so I feel if I became someone's someone, I'd actually make a good girlfriend. If u thought its probably I come clingy, in fact, I'm not clingy at all, I give men their independence to appreciate mine as well.
My flaws, maybe cuz I'm super-talkative, super-analytical, I'm kinda jokative, awkward when faced with strangers & turn up all silent, & lastly, I hate using social media, plus my relationship with my phone sucks.
So please you guys, I want your help, I'm in a dire need to know what causes my problems of pushing my crushes away once they actually start liking me, one went away cuz he thought he found my friend whom he thought was better than me, I honestly don't want to feel lower than all girls in the world & I wanna go through the dating world because when I happen to really like a guy, I wanna know how to approach him without him disappearing & me getting sad.
