But that's how it is for a lot of men who get nothing their whole lives. Anything is better than nothing after an entire life of nothing. The men I'm speaking of will take anything. They can't afford to be choosy because if they do manage to find someone else who shows interest in them, it's likely to be their only chance of getting anything. Beggars can't be choosers!
But wouldn't you consider wondering why someone is taking an interest? it's the first thing I wonder (even though I've been fairly active in relations in my adult life)
And honestly, if you're not wondering that, if you're middle aged and suddenly get harassed and settle for that, you might have other issues going on. Self-worth being one.
