Did Jasper and Maria have an intimate relationship?

Answer 1

The answer to this is still unclear. Stephenie Meyer has said that she would use the movies to clear some things up, as in, questions that fans keep asking. In the books, Jasper never said anything being in a relationship with Maria, other then helping her with the newborn army. In the movie, however, we see them kissing and he states "I thought what we had was love".

In my own personal opinion, this says that, yes, they were in some sort of relationship, but Maria had ulterior motives. She used Jasper's age and inexperience with women to make it seem as though they were in a relationship, but used it for her own ill gain. (Just like Victoria and Riley.)

However, if you mean intimate as in a sexual relationship, Jasper has never said, so we have no idea. Remember that he was a very proper Southern boy, so I think we can safely assume that his virtue went to Alice.

Answer 2

Jasper and Maria did have a close relationship but it was not intimate in a romantic or sexual way. They had a strong bond as partners in their pursuit of creating a newborn vampire army.
