Did he dump me because I'm ugly?

Well a lot of guys have asked me out and told me I'm pretty...I.wish I could provide a pic but I'm not allowed to...I have brunette hair,big brown eyes,I'm kinda lean,I'm pretty tan,I have high cheekbones...in an odd way I'm like a cross between Spencer from pretty little liars and demi lavato (however its spelled)...well...I know my ex liked my personality so is it because I'm ugly? Yeah, I know how pathetic this sounds and it kind of sounds like I'm big headed but trust me...I'm super self-conscious!!! Please help me :(
