In a modern new age ruling someone might make that jurisdiction. Tradionally you look at your 7th house for your marriage partner.
In your case you have 3 signs in your 7th house. Capricorn on the cusp. Libra middle. Scorpio at the end. So really mercury, venus, and mars are going to control your 7th house. With Mercury being the strongest
All 3 are going to manifest to create your love life.
Then your 5th bouse is in cancer ruled by the moon.
So yeah in your cause that venus moon opposition does translate into a 7th 5th opposition. Not a good sign for someone who has no planets in either house
Still doesn't mean you won't get married. Just that marriage and relationships aren't the most influential things in your life.
