I wonder if you have addressed your personal issues for freedom to do whatever you want when you want to do it, as evidenced by your fairly powerful Uranus that is also out of bounds by declination. With Saturn opposite Mercury there are issues, and with Saturn so prominent in your chart, it is difficult for you to shift in mid-steam which is one of the essential characteristics of relationships.
While I am only a beginner in astrology, I see a lot of potential issues in your chart which would interfere with your ability to sustain relationships because relationships no matter how they are configured require you to often go 75% for the other person. Going more than 30% for someone else would tend to constrain your extreme needs for personal freedom of action. You do not like having other people have any control over your actions, and that is what relationships consist. You have to be willing to go with the view of the other person even if you may not agree, and be willing to pick your battles. You cannot win all the time.
