Mars opposite to venus?

I have read this several times and I know that for perfect match making full horoscopes are needed. But I don't have the birth time of this man. But I know this for sure that I have Mars in Taurus and he has Sun, mercury, venus and Rahu in Scorpio. Scorpio is 180 degrees ( opposite to ) taurus.

Please tell me if this is a hint that when my mars is in opposite sign to his Sun, venus, mercury and rahu, then what is a indication of serious love, attitude and personality clash, which will end up being a, if not abusive, but frustating one. I see him as a good man but you know how people can hide their anger before marriage and takes the monster in them out afterwards. I want to be safe that's all. Don't want to get trapped in unhappy relationship.
