Which townie has been the best romantic partner to your Sim?

Oddly enough, even with his commitment issues, Don Lothario! He's a great and attentive daddy to their children and never even flirts with other sims (I thought that was strange) But unlike Jay Huntington, he just gets the urge to change jobs all the time. I've never even had him roll a whim for flirting or woohoo with anyone but his wife. Also, the kids that come from them are adorable. :)
