You won't have his heart if you don't open up, that's for sure.
His chart:
First, his house of one-to-one relationship (7th house) has Gemini on the cusp. He probably seek and is attracted to people who're either very intelligent or very childlike in appearance. With your Cancer Ascendant however, you may have such appearance (think Selena Gomez). He probably like his S.O to be younger than himself or at least act like it.
He wants someone to see him as a teacher and someone who adores him, and flatters him (with his Leo intercepted he NEEDS that - someone that gives him attention to boost his ego). He may however be the one to quickly run away once you can't keep him mentally stimulated.
You both have Mercury in Capricorn so you think alike; consider any situation arefully. However your Air-energy is pretty low, so you might have trouble keeping him mentally stimulated.... But I wouldn't worry about this, because it seems like his Air-energy is low as well, and he just wants to feel that he's being admired.
I would have to read his chart seperately to know if this is exact.
Aspects:
Ok... Now, correct me if I'm wrong with my observations, lol. I might have mistaken your Mercury with Moon or the other way around.
His Venus/Mars conjunction Trines your Moon:
You're quite happy with compromises, but sometimes you may stay silent out of fear of upsetting him.
There's a natural affection and this aspect probably means that he likes you too.
This aspect is very positive if you hope to have a relationship with him. With some effort, the two of you can create something beautiful and share friendships.
Your Moon Trines his Moon:
(It's actually quite satisfying writing this, haha)
You most likely share similar tastes, and you feel comfortable with each other. Each of your families might also play an important role in your relationship.
Your Venus Squares his Pluto:
Intense and magnetic attraction. Strong aspect that might indicate a long-lasting relationship, but with an emotional rollercoaster ride that swings from intensely loving to hostile. Jealousies can arise when you're apart from each other.
His Moon is in Opposition your Pluto:
Magnetic sexual and emotional attraction to each other. You bring out emotional responses from him - you can see right through him and somehow bring out his most intense, secret emotions. With this aspect he might feel obsessed with you... Is this good or not? I'm not sure... He might get addicted to the emotional intensity and is eager to please you (intesified by his intercepted Aquarius that makes him give, and give, and give...)
Usually Pluto (you) has the 'upper hand' in the relationship, which is quite the opposite of the reading I did with your chart seperately.
He may feel 'controlled' or manipulated... but nonetheless, you both will fear losing each other. If any indication that he'll lose interest in you or leave you, you'll most likely be the one who causes a strong heated and emotional battle.
To be honest, reading the last aspect makes me quite surprised... Reading your chart you don't seem to be somehow who could be manipulative, but rather the one who would get manipulated.
But this is what I found... Maybe it's because you crave a relationship so deeply that being in one can change you to become manipulative or be in control, just to make the relationship survive.
His Pluto sextile your Sun which basically says the same as the above ^but with the roles switched... Unless it's your Neptune and not Sun - again, it's hard to tell. v_v
Pluto sextile Sun leads to personal transformation.
There's some other aspects I didn't look much into. I believe the most important planets you look at are: Venus, Moon, Jupiter and Saturn.
Doesn't look like your saturns are aspecting each others charts. I tried to read both your Venus and Moon...
..And Jupiter... Well your
Jupiter trines his Pluto: telepathy, transformation, transcendence, spiritual ties. Quote: "
He will use intensity to help you undertake challenges, and to create or recreate your relationship into one that transcends obstacles and brings happiness to you both."
and your
Jupiter also is in opposition to his Neptune:
Quote: "
You will expand your roman partner's creativity and ability to dream, giving him faith in a brighter future. You draw inspiration from your partner's seemingly bottomless creative well and believe that you two can accomplish anything together. "
pheww.. I started to get tired reading the last bit, so it might be messy. If you have questions to any of it I will gladly search for a bit more information.
