Is he just not interested, afraid or really too busy?

I got back in touch with a guy from high school (we're both in our mid-thirties) after we kept running into each other and he'd suggest I call him.

I finally did, we spoke by phone, had drinks one night (he invited himself after hearing I was nearby and alone there) and then he showed up at my house to mow my lawn, see how I was, etc. I was in the middle of moving and he's in his busiest season at work.

Thing is, although he only lived 5 minutes away, in 6 weeks of almost daily phone calls (initiated by him) we have yet to have one "real" date. When I brought it up a few weeks ago, he said he was way too busy with work right now & I was busy with my move, etc yet I've tried to find time and make myself available to see him even if just for a few minutes to say hi but it's almost like he's avoiding being together in person unless it's to come fix something or help me around my house or something.

When in person, he holds very long, deep eye contact, seems very interested in all aspects of my life, body language indicates he's interested, etc but he never has time to even ask me out for a drink?

This guy did have a traumatic accident 8 years ago and a heart attack 8 months ago but has also been a bachelor all his life.

Almost all signs indicate to me that he is really interested and yet, no dates, He works 7 days a week for an insane number of hours and seems to think only about work. Summer is his busiest season but if he was really interested, wouldn't he find time somehow?

I really care about this guy and am trying to be patient, understand his busy schedule and consider that maybe he's working so much and staying distant because of fear but I don't know anymore. He's also had both parents pass away from very debilitating diseases; Parkinson's and cancer and he's now had two close calls with death himself.

We have had sex twice already, the chemistry was there and we both wanted it. He was very caring and I've known enough guys to know which are just using for sex and I totally do not get that impression from this guy. The sex was great but if anything, it was me initiating it more then him even.

I don't know if I should just give up or be patient? Any thoughts would be so appreciated. I'm just totally at a loss here.
