This "fairly overweight" woman looks pretty average to me. In fact, I wouldn't have noticed her weight if it wasn't pointed out. She is a single woman who is subjectively attractive and she has a good job and a house. Nebraska isn't the acrctic-she lives in a metro area that has a pop of almost 1 million people. 38 isn't akin to being dead on the hook, it is barely even middle aged and even then it doesn't mean women are no longer desired. Unlike in Hollywood, in the real world women continue to love and live fulfilling lives and attract men even after they leave their 20s.
We don't know how hard she looked for a man or if she even looked at all. She met Mrsa in a beekeeping group, not on a dating site. The fact that she is trying to marry a foreigner does not mean that she went through the entire Match.com database for the midwest and was turned down by everyone.
