Before the prequel trilogy, I always assumed the reason you didn’t hear about the Jedi having love lives was because they tended to be hyper-focused on their vocation, but if a Jedi were to fall in love it was no big deal.
At no point in the OT did either one of Obi-Wan or Yoda say to Luke something like “Now that you have chosen this path you must forsake any notion of a love life. Your father violated this.” or something to that effect.
