I agree with Elena's assessment. I will add something else I see in his chart too.
His chart type is called a bucket, and the funnel, or the focus point, is through his Mars in Cancer in the 8th.
That means that all of the energy in his chart is funnelled though his Mars in the 8th of sexuality/intimacy. So I would imagine that he is very charismatic and sexy and he might use that to his advantage. Who wouldn't? lol
But his Mars is trine Pluto in Scorpio in the 12th. of hidden agendas. So I worry that he might be kind of manipulative and mysterious.
I know that you like him. But he may not have the purest of intentions. Take the time to really get to know him because he may be just going for the physical goodies, and will then walk away. Watch and see if he does that to others before you take the bait.
Also, Mars in Cancer can be moody and easily insulted, so watch and see how he operates emotionally. He may manipulate others by dragging them into his 'guilt/pain' victimhood, where others try to soothe him or heal him. Watch carefully...
If you stick around long enough and build a strong emotional connection you might be able to get past his walls. If not, you might end up as another of he ex partners...
