Hmmmmmm.... Ok...I would love to be all sunshine and rainbows - and tell you nice things, because I can see you are excited about this guy, but I have to be honest with you... and I find the connection between you difficult.
I wouldn't say it's extremely challenging, but there are some issues.
First of all - I'm not one to care about the age gap, because I basically think "age is a number" for anyone 18+.
However, considering your particular placements... I'm not sure that this could work out as a romantic relationship or a fling.
There is definitely an attraction, which I believe would be mutual - so that's a nice thing to have. There can be flirting between you and friendly banter.
But I'm just not sure that this will take off.. or become more serious than that.
I'm saying this because... first of all - His Aquarius Venus retrograde.. is a difficult position for Venus.
At his age - (since he is young).. and having such a complex Venus placement (which is also square his Moon sign) - he won't be an easy guy to date, for *any* woman.
This isn't just about you. This is about any woman under the Sun who comes in contact with him.
He definitely has some pretty *big* problems and hang-ups romantically, that are not easy to resolve - and it might take him a long time - or a few more years at least - to get some control in this area of his life and feel a sense of balance.
Due to the Moon/Venus square.. and the fact that Venus is moving backwards/retrograde... He can be both indecisive and send highly mixed signals. It's likely that his ex gfs would tell you - that he drove them up a wall with the flip-flopping.
He is also never completely sure whether he wants a mere friendship, or something more than that.
You, on the other hand.. having signifiant placements in Libra and Scorpio and also being female - you seem to have a MUCH better handle on "how to have a healthy and loving relationship with another human".
Having friendships and relationships.. getting close to another person... is not something that is all that challenging for *you*. Or, at least - by contrast to him... you are much more approachable, much more loving and much more open.
In a sense I could see how - getting closer to you - would be a good experience for him.. because there is a lot that he could learn from you, and the way in with which you interact with other people, and get close - and develop a bond - over time...
He does not know "how to" get close.. He does not understand the watery depths of your Scorpio Venus...
For instance, the concept of "making love" is something he read about once in a book somewhere.. and it likely went in one ear and out the other.
He can be poetic though... He might have a "way with words".. and he might seem deceptively romantic on a surface level - but don't be fooled... because you are a *much* deeper person than he is on an emotional level. His pretty words can truly be *just* words.
While I do feel you might be good for him... I can't say that I feel the same way vice versa...
At the end of a relationship with him... in my opinion - you would feel grateful for being able to feel - As strange as that may sound...
You would actually think to yourself.. "Wow.. I'm so blessed to be able to *feel* and to have a heart.. because there exist tin-men in this world, with hearts made of stone - who do not have this amazing ability". And you would end it feeling sorry for him... and moving forward.
I think you would be happiest in this situation - if you kept it at a more surface, flirting, friendship.. sort of level... rather than trying to turn it into something deeper.
I also think that - for you - this is more like a crush.. My gut feeling is that you find him physically attractive and particularly good looking. Because I can't imagine (based on the synastry) that you would be very drawn to him.. if he was average looking...
I am saying this purely based on the info I have though.
With a correct time of birth - you can see how the individuals angles match... and also the Vertex axis.
If this is deeper than a mere attraction - if it's a soulmate connection or a past-life connection... the angles would tell that story imo
But from what I am seeing here.... I'm just giving you my honest two cents.
If you like - post the composite chart as well!
That could also maybe explain more regarding the attraction... if you truly feel like this a significant connection...
