Jedi can retire and have families, but most Jedi stay in the order their entire lives. By the time they leave, they will be too old to raise a family. But it's not unheard of for Jedi ti marry while in active duty. You have to receive blessing from the Jedi Council, but it's a tough sell. Only Jedi who have proven they can handle the feelings and burdens love brings are able to marry. It's a very strict process.
any example of jeddi marriage besides anakon? in the comics , satele shan have an affair with someone and bore achild, but because she is afraid of the jedi , she abandon the son.
do the lore also state that a jedi can quit jedi order , but still retain his lightsaber and his force powers even in civilian life?
