There is a very little knowledge and understanding on the outer planets. Uranus is not quite so simple. Uranus wants liberation, it wants spirituality, knowledge, the "New Age". So Uranus in 7th doesn't always has to mean what UnluckyGirl said. Sometimes i just means an unconventional relationship. And unconventional these days can mean a lot of things. Twin flames are unconventional, for one example. Or you taking the role of the male is unconventional. It might simply mean you can't be a "wifey" and you might need a relationship with reversed gender roles. It might mean your partner will definitely be weird. The one that's the weirdest of them all and does not fit the social norm, that will be your guy. A visionary.
Also if I got your chart right, Uranus is aspecting much more the 8th house rather than the 7th. THe ruler of your 7th being in 3rd, and being Jupiter, you might indeed have a partner that's not from your area or background. Could be a foreigner, or someone simply from another town/city. This is unconventional.
Problem with Satrn opp. Venus, is that Saturn wants maturity here, being in Aqua in 9th, and Venus in Leo in 3rd wants to just have fun, and make everything dramatic and flamboyant. A conflict arises here. However, Saturn opposite Venus is not nearly as harsh as a square, it simply needs a communication. There needs to be a balance somewhere in between. Saturn is at its home in Aqua, however Aqua is also ruled by Uranus. SO you might need to come up with unusual and unconventional ways when it comes to your relationships. You have the potential to do so, definitely. Just don't try to fit any norms or try to be "normal" or have a "normal" relationship. Not gonna happen, you were born to be different, so embrace that! Each time you try to be normal, you will feel miserable.
North Node in 8th house indeed is a bit difficult path to take, but definitely not impossible. ( I have that too). For you it will be best to follow a spiritual path, since this node definitely will demand that. There you will find love.
UnluckyGirl made an interesting observation about mostly Capricorn/Aqua/Saturn/Uranus asking for relationships. Now... lets delineate that, so you get a better understanding.
Capricorn/Saturn is one who is a traditionalist. However, Capricorn is known for breaking and reforming the statut quo. Aquarius is also rulled by Saturn, but also by Uranus. The liberator and destroyer. When we combine all this? Relationships are experiencing a reformation, transformation, love is changing and becoming freer. After all we ARE enering the age of Aquarius. We are letting go of so many old chains, old belief systems of how love should look like, how it should be, what a normal relationship should be. Uranus and Saturn are gonna say "Aw **** that, there is a new and better way!"
All you have to do is shift he paradigm of your thinking and perception, and you will see magic happening in your life!
