25 M - Am i unattractive and creepy?

I've been going to the gym to lose weight and I don't know why but i get zero matches and nowadays whenever i make move i get rejected making me feel I'm not wanted and unattractive. Is it because of my height (5'8) and my looks? Do i look creepy? I've had partners in the past but I always had to push and carry all the responsibilities in general and yeah... You know I've been single because i wanted to get better with myself. Any suggestions?
