Didn't watch it, but I can imagine if one's love life has been a 'desert', as I would think would be the case for many on such a show, that one would be happy with anyone who took and interest. Might change one's mind later though.
Also, if one has a choice between two great folk, both equally nice, and one of them has issues, what would make one deliberately opt for the more difficult life; save an inner need to help maybe ? I think most folk tending to opt for the less demanding option is inevitable, and ought not reflect badly on the general public.
