Would aqua guy even care if he ever saw me again?

I have had a big crush on this aqua guy for over a year now (his moon is in aries). He is in his late thirties and has never been married, and I actually met him in connection with a transaction regarding the purchase of my new home. I definitely felt a mutual attraction from the start, not just sexual, but also to the point that I could at certain points almost hear what he was thinking. After our business transaction was finished, he sent me a cute mail with a picture of his dog, saying he would like to stop by at my new house with his dog, who was always happy to meet new friends LOL!! (his best friend actually lived on my street!!) Of course, I wrote him right back and said he was welcome any time with or without his cute dog, but that I was leaving for Europe within a couple of weeks.
As a cancer/leo cusp, I obviously thought he was a normal hot-blooded guy, and that he would stop by, which he never did. We actually had some kind of e-mail interaction in which he said he would stop by that and that day, but he was not sure what the plans were, but he never did. I saw him drive by my house several time, and he used to have these huge sports stickers on his cars (he played professionally at some point), which he removed after I one day was driving right behind him while he was passing by my house!

I was heartbroken all summer, and then in the fall, out of the blue, he called me up to just see how I was doing. I was a little cold on the phone, obviously. Since the new year things have started to warm up again. We have had another business thing going on, and had a many meetings at his office, half of which was in no way necessary. Then at one of our meetings, he let me wait outside for twenty minutes while I could see he was chatting with a colleague. When he finally was ready to see me he was sooo cold towards me, which I just didn't understand. He asked how my weekend was, and I told him I had some friends over for the weekend (a whole family), and he said that he had noticed a red car and a guy and a young boy playing basketball in front of my house. I left the meeting kind of distraught, but afterwards it occurred that he probably thought that the guy was my boyfriend!
Since then, I feel that he slowly started to open up, and we have actually been e-mailing every few days, with the excuse of doing business, but also just to check in on how our weekend , etc.

Every time I have had to stop by at his office with some paperwork he has been sure to tell me exactly when he would be in his office, so I could stop by and say hi. He got so excited when he found out that we have mutual friends. He suggested to stop by to pick up some paperwork at my house last week, when he had to go to his friend's house, but it didn't work out since I wasn't going to be at home. Our business transaction is now totally finished, and when I had to stop by last week with the last document, he had said he would be in his office all morning, which he turned out to not be. I e-mailed him just to make sure he got the document anyway, and he sent back a really nice e-mail saying he was sorry he missed me, etc. However, I have not heard back from him since then, and I have not contacted him either.

I really, really have strong feelings for him, and I do think I got him to open up to a certain point, but I am not sure if I should just leave it at this and hope that he would somehow make a move on aqua time, or if I should continue trying to stay in touch without putting any pressure on him. I am not someone to pursue a guy, and, yet, somehow with him I seem to have already. What do you aquas think?

You are right, Paper-folding-enthusiast, I have to be more direct and flirt--I guess I just don't really know how, except with body language (playing with hair, looking into his eyes, etc.), to which I understand aquas are impervious.

Hotlovinggirl, his venus is in sagittarius, as is his Mars. My ascendant is is in sagittarius, I don't know his. For me venus and Mars in cancer (help!!!)

Our business dealings are finalized, so for all I know I may not see my cute aqua again. Thanks for all the advice. I think I will drop off his performance evaluation (which goes directly to him) with a cute flirty note, telling him to have a wonderful summer, if I don't happen to run into him on my street (where his best friends live). I don't know in aqua language how that would be interpreted (as if I never wanted to see him again—) Any better suggestions--since I don't know how I would just drop by at his office and just start flirting with him.

aquaj is right--he is late 30s and has never been married. That should serve a a red flag. I think he just values his independence way too much to give up even a tiny bit of it. Not that I am looking for anything real serious at this point--I am actually learning to value my freedom and indepence myself, after having been in a twenty-year relationship with a real control freak.
