Jedi love

Jedi Love is a practice that was forbidden by the Jedi Order during the prime of the Jedi and while the Old Republic still stood strong. The reasoning behind love being forbidden for a Jedi Knight was a combination of many factors, but the most prominent and probable cause was that it had been observed in the past that whenever any form of attatchment was allowed among the Jedi, it would often lead to fear of loss, jealousy, greed, anger, hate, and ultimately the dark side; The same reason for taking the force-sensitive children from their families at an early age. Any time a Jedi has a reason to feel aggression, it is considered a danger.

The practice of romantic relationships involving Jedi was revived after the fall of the empire and the ultimate return of the Jedi, mainly because the amount of force-sensitive individuals were so thin at that point that offspring were necessary to continue on the Jedi bloodlines.

Forbidden Relationships
While many Jedi during the Old Republic's rule followed the code placed before them and did not act on their personal desires, there were at least two instances in which the code was broken, either in confession of love to another, or a complete relationship. Anakin Skywalker confessed his love to Padme Amidala during this time, and ultimately married her in secret. Qui-Gon Jinn also confessed his feelings for another, in Jedi Master Tahl, just before she died.

Allowed Relationships
There were two eras in which Jedi Love was completely allowed; the first was during the birth of the Old Republic, and the second was after the fall of the Empire. In both cases, the most well-known relationships were that of a converted Darth Revan and Bastila, as well as the much later on marriage of Luke Skywalker to converted Sith Apprentice Mara Jade.
