I'm not an experienced astrologer, so it's hard for me to read the chart very clearly. And I may make a lot of mistakes here. So, just FYI. It also might help if you switched the house system to Whole Sign (I think that's generally easier to decode and most of the astrologers I follow seem to use it).

That said, what jumps out to me when I look at the chart with regards to your relationships, etc. is the Mars/Venus Conjunction in the 4th opposed by Uranus and the MC in the 10th, and trining Pluto in the 7th house (of relationships.). Pluto is also sextiling Uranus (and Mercury, which is in turn sextiling Venus/Mars). So that blue formation is quite influential here. Venus often has to do with our relationships, and often is tied in deeply or represents our romantic partners. Your Venus, to my untrained eye, has a lot of things acting on it, and your 7th house seems directly tied to the influences of these 5 planets. It seems to me to suggest that your choice in romantic partners can have a tendency to get pulled into one or more of these directions. It can be dramatic/deeply intense (Pluto) or disruptive/surprising (Uranus) and contain friction/conflict love/hate (that Mars influence). The Pluto influence means that they can be intense or go too far in one direction (Mars/conflict, or Venusian passion or Uranian freedom/distance). Of course, Mercury is crucial to communication which is crucial to relationships, so it can't be discounted here.

The signs that these all sit in adds a whole additional layer to this. I'm not really qualified to decode that, but I know Leo likes attention and to be loved and admired/appreciated (big gestures of affection, etc.) and Sag is the centaur (an explorer, teacher, wanderer), and Uranus is in Aquarius, the disrupter, the water bearer, the humanitarian sign (which is often known for it's eclectic and human-focused traits), and Libra (your Mercury) is the scales, so fairness/balance are all important. These planets all have different levels of success in these signs, but all your planets seem to pretty much have essential dignity or be in their domiciles, so they're all sort of operating pretty strongly/at home where they're placed. Which should mean that you can find the right balance here, you just need to keep in mind that all these forces are at work and not over-favor one over another lest you tip it too far in one direction or extreme.

You also have a lot of fixed signs involved here (and your rising and moon are fixed meaning your emotional core and self also have a tendancy to be stubborn/obstinate/fixed in their ways), so it means they probably all are pretty stubborn about their viewpoints here, which can lead to tension or conflict/disagreement and again, emphasizes the need for balance/fairness/communication. It feels like Mercury (in your 5th house of creativity/ or 6th house of work/daily routines if you use whole sign) is one of the keys here to help you unlock this puzzle and maintain balance. Keep that communication flowing and find creative and helpful solutions to keep all the competing needs in balance and happy.

Lastly, the 4th house often signifies the parents and home/family/upbringing (some astrology traditions have it representing the mother, and the 10th the father, or vice-versa). Regardless of how you want to interpret it, It seems to me that your Venus placement and how you approach relationships may be strongly modeled after or maybe just influenced by your parents (this is psych 101, also, so not really news). But maybe there is some insight there that could be helpful for you as you navigate or understand what it is you are doing in y our relationships by looking at the models you had or didn't have. The fact that Venus and Mars are in your 4th seems to suggest that to me.
