My fiancee doesn't really care. We started dating when I was at my SW three and a half years ago. I just lost the overwhelming majority of this weight very recently and he doesn't really care one way or the other.
He's also tall and thin, so I understand the feeling of "what? really? He's
interested?"
Before you jump back into the dating pool though, you might want to take some time to yourself! Learn to love yourself and become confident in your own skin. Confident people—regardless of their size—attract people (friends and lovers alike).
Before I met my fiancee, I was in a relationship where the guy nearly took advantage of me because I dated him for the sake of dating him. I couldn't believe
anyone was interested in me so I jumped at the first guy that showed interest and I got my heart broken. After that relationship I took some time to myself and really came to love myself. I found that suddenly men were interested in me when I became confident in who I was! All kinds of men! I remember having to deny a few of them because they just weren't what I was looking for.
Then I met my fiancee and we've been dating ever since.
So take some time off, find out who you are and learn to love yourself even now
The relationship will come later, and you'll have a better one because of it.
