SINGLE FOR LIFEEEE in Emotional

I’m 21 and have never had a boyfriend. Seriously. Not even in high school or middle school. You might say oh who cares youre young, you have time. Yeah but being a hopeless romantic, this is all I want in life. I put love above everything and would do anything to find it. But, since I’ve never had someone to love me back, I’ve been in love but they thought otherwise, it really puts a toll on my self esteem. Think about it. no guy that i’ve ever been interested in has ever wanted to take things further with me. And i’ve never been able to change their mind and have them consider making me their girlfrined. do you know how that makes me feel?? it amazes me how couples can break up and then a couple of months later one of them will be with someone new. like how?? I can’t even find one person UGHHH
