thoughts on this sag guys placements?

Long story short we've know each other for ten months, met on a dating site. We are not exclusive, yet he's mentioned a few times he wasn't with anyone else "too busy lol". ( I never asked, he volunteered) He has a very demanding job, typical sag workaholic. I joke that hes married to his job. When we first started talking he had just ended a long term relationship. we've kept things casual, we talk every few weeks, he's the one who initiates contact most of the time. I am curious about his placements, he seems to be a "quiet" sag. In fact the first time we went out i thought he didn't even like me. I'm good at reading people just not him. Until he blurted out he thought i was gorgeous, and was back to stone face. In some ways he seems so shy/reserved but still not afraid to go after what he wants. the best way i describe his is still waters run deep. we don't see each other often at all, but he's always the one who resumes contact. Only recently, have i started contact to switch things up.

Any insight to his chart would be most helpful and appreciated. I don't know his time of birth so i don't have his rising.

I noticed he has lots or retrogrades, and wonder how that changes things from the traditional.

thanks again for any help you could offer 😄
