Does this Scorpio man like me? I cant tell. never dated a scorpio.?

Two weeks ago, I posted a personals ad looking for a man. A scorpio man replied and within a couple days we were on our first date, 'drinks & talking at a local pub' we ended up making out in the end, and he dropped me back home all within a few hours. It was a nice afternoon date we text flirted a few times after & soon made plans for lunch a few days later. He was working but he wanted to grab me & take me for sushi on his two hour lunch break, which he did and we kissed then he dropped me off and back to work he went. A few days ped w/text flirting and i invited him over for dinner & movies. The night went great, we made out thats as far as it's gotten, it was hot! then it was past midnight and he had to return home for bed due to work early in the AM. He later thanked me said 'he had a great night!!!' So it's been a 4days&I've received no texts & although I know he's been working 4doubles in a row covering for someone on vaca shouldn't he have texted/called if he was interested?
