Venus conjunct Pluto in synastry:

 Romantic and sexual attraction is very powerful, but is likely to have an intense, obsessive quality as well.

Jealousy, sexual manipulation, or unrestrained emotional fervor are strong potentials between the two of you. An almost fated, love-hate kind of relationship is very possible.
