Are there any women out there who actually find me attractive?

I'm about 6 foot 1 and am roughly 250 pounds. I don't really find myself attractive and often wonder if women actually find me even slightly attractive or if I'm just completely ugly.I often don't get a chance to show my heart and personality as I use online dating and often get rejected because of my appearance, but I believe it's a man's duty to take care of his lady, respect her, always be open and honest with her no matter what, and always stand up for her, stand by her side and support her and do what it takes to make her happy.
