What “other” options are we talking about? Blowup dolls? Actually the more I think about it the more appropriate it sounds for some of these poor schlubs. :-)
Not getting married. Finding a woman (or series of women) willing to be an unmarried girlfriend, and NOT intermingling finances.
As far as housing, either maintaining separate residences, or the guy moving into the woman's house. While together, he may contribute his share of the living expenses, but if the relationship ends, then he moves out. She keeps the house, but his financial support immediately ceases and she pays her own bills at that point.
LOL....how funny!
