Hi, Bonnie,
I think I understand what you're saying. The facets of weight loss involving clothes, health, etc. are a lot more "knowable." The romantic aspect of weight loss is completely "unknowable." You lose your safe cocoon, where you don't have to deal with the very real complications, yearnings and tough questions that come with romantic involvements. I connected with your post in a very visceral way as have the others who have posted -- the romantic aspect has had so much to do with my inability to lose weight!
I was successfully losing weight at the time of my husband's unexpected death in October of 2007. I tried a couple of times after to lose weight, but I just couldn't get the momentum going. Something was stopping me, and it was exactly the concerns you describe. Every time I began to lose weight, I began to feel attractive again -- and suddenly I felt disloyal to the memory of my late husband. I just wasn't ready to be a sexual being again. Accepting that potential was my biggest hurdle to successful weight loss, and it hasn't been an easy one.
It DOES change everything. It means coping with a whole new set of issues -- and although they may be exciting, they're still issues! And of course the other, unspoken question... what if it isn't enough? What if, after losing all this weight and putting myself through all this, I discover I'm still just not a very attractive person?

Ut-oh!!!
I think this is why we need to make peace with the notion of losing weight for ourselves and nothing else. Not for the relationship potential. Not for someone else. Not because we might become "beautiful." And not because, goodness knows, it will solve all our problems.
I decided I needed to lose weight chiefly to improve my health. For reasons unknown, suddenly lots of men have turned up. Something in the cosmos... I don't know. It's not like it's easy for me to meet people, since I work from home and I live in a very rural situation. I may only leave my house once every couple of weeks. But 4 different fellows are making overtures (only one of whom I'm genuinely interested in), and I'm just taking that all as it comes. I enjoy the attention, set the agenda to suit myself and keep going with my plan to lose weight for health. The rest of that stuff is just going to have to sort itself out! Funny thing; the more self-confidence I demonstrate, the more interested they seem to become... and I'm not even close to my "slim" category. So based on that, I've decided that it has a lot more to do with what I'm putting out there than my weight. Consider how many pleasingly plump ladies here enjoy wonderful marriages -- could it be that we're all wrong about the weight thing? Maybe, or maybe not, but I know how *I* prefer to think of it!
This is getting really long, but I'll share one last story that I hope will help you... the man in whom I am truly interested is a man from my past. We shared a strong attraction some years ago, but situationally it was impossible (he was married). We met up for the first time in about 8 years this past September -- I weighed 100 pounds more than I had the last time he'd seen me. I dreaded that first meeting. He didn't even notice. We met up again earlier this month and I'd lost a quarter of my hundred pounds... again, he didn't even notice. He still just sees the girl he cared for long ago. Based on that, I really think it's more to do with who we are inside, and less about the packaging. If you can keep that firmly in your mind, it may become easier to deal with it all. I do hope so -- and if it helps to talk, I hope you will keep posting!!!
