This will be very easy in some aspects and quite difficult in others.  she has cancer in her sun which makes her sensitive and gentle and the leo adds energy and determination, the aries will cling to the leo in her and bring it out but if you spend too much time together without communication the cancer can end up completely ignored.  Your risings are greatly compatible, when you are spending time with others things will go great!  Your friends are both gonna like the other and when you all hang out together you’ll both work well together and keep everyone entertained!  Social gatherings will be very successful for you both as a couple!  The girl will be charming and fun and the guy will be energetic and almost like a walking talking commercial!  The moons aren’t compatible but they don’t clash.  The girl is likely to have a desire to travel and a very restless undertone in all she does.  She dreams big and has a definite feeling of “wanderlust”.  The guy is more composed and attracted to comfort.  Neither are sloppy and overly emotional but neither are cruel and insensitive but they both gravitate towards different directions.  A lot of this match is about finding a good balance.  The guy needs to learn to appreciate the girls sensitive side and she needs to be able to comfort him and help him feel stable without crushing her own dreams.  Best wishes!  Namaste!
