Robots need love too...

In Piers Anthony's novels (the series that starts with Split Infinity and Apprentice Adept) there is "true love" between a human and a robot woman.

No computer to date has passed the Turing test, so "true love" with a robot is probably beyond the horizon (if science fiction has taught us anything, we'll have to wait until the year 20X6 for that). However, it's not out of the question.
