In the Clone Wars series he has a semi romantic relationship with the Duchess Satine of Mandolore. Around the end of series 5 Darth Maul takes over and executes her as part of his revenge against him.
I think a better point to make is that he brings death wherever he goes. If you want to live, don't let him care about you... or did I miss the point entirely? ;P
