No, not even himself: he willingly destroyed his own soul.
No. Lord Voldemort was incapable of love.No.
Bellatrix Lestrange was the closet and most devoted servant of Voldemort. She was also in love with him but Voldemort couldn't love.
Voldemort is incapable of love. This is why Harry is able to defeat him.
If he did, it was not mentioned in the books. It did not sound as if he ever did though. It was mentioned several times that Voldemort was incapable of love, and it seemed he was too busy trying to rule the wizarding world to have casual flings. i don't think a girl would even like voldemort.
Due to the fact that Lord Voldemort has torn his soul into several parts it is safe to say that a love potion would not affect Lord Voldemort.
Voldemort is a man, therefore he cannot be a lesbian.Considering that Voldemort never cared for anyone but himself, it is doubtful he ever formed an attachment to anyone sufficient to define his preferences. He was only in love with himself and obsessesed not with sex, but with power. He certainly would not have been above using someone else's proclivities and preferences against them, but he would have considered anything as trivial as sex to be beneath him.
Bellatrix is really in love with Voldemort, however the feeling is not mutual... He just uses her for his own personal gain.
Nobody. Voldemort doesn't understand love and therefore does not love. However the closest things he ever came to loving were Nagini and hogwarts
All I know is that Voldemort was based on Hitler because Voldemort hates anyone who is not a pure-blood, whereas Hitler hates anyone who isn't a Christian
No. Voldemort never gets married in the book series nor in the movie series. A major theme throughout Harry Potter is that Voldemort does not understand love and marriage in Harry Potter's world appears to be something characters do out of love (with a few exceptions like Bellatrix's marriage as she was in love with Voldemort but he did not reciprocate). Therefore it is implausible that Voldemort would marry for love. If he did marry, at all, it would be for convenience alone and as this does not seem to exist in Harry Potter's world, it is implausible for that reason.
No. Lord Voldemort killed Severus Snape's true love.
Probably. He was incapable of love.
