I had something similar once. Neighbor man (over the fence backyard neighbor) knocked on my door late one evening with a small gift in hand, Oh, did you know my wife and I are broken up? Nope but thanks for the candy. Goodnight.
I guess guys think we should find this flattering but we don't regard it as flattering that because you and your old lady are having issues that you think of a woman that lives alone as your next-door dating buffet. You are now the creepy neighbor. Congrats.
