Changes in demeanor

Do libra's usually emotional once they start liking someone? Because over the past month that i've known him, I've seen such a shift in this libra guys behavior. He started off very flirtatious and blunt, then after the first couple times we hung out, he seemed to tone it down. He still flirts but it's more subtle. And instead of asking me to come see him, he'll now hint at it over and over again until I either mention wanting to see him too or straight up ask him if he wants me to come over. And goodness forbid that I can't come see him the moment that he want's me to, he suddenly turns into the saddest and most disappointed thing that I have ever seen.

Then the other day, I went to hang out with him for a bit because he started texting me how he was was super stressed out with work issues, plus l could tell he wanted me to come over but of course wouldn't just flat out ask me to (and i wanted to see him anyways). The interesting thing though is that, to me, he seems to be opening up more and offering up details about his life that I didn't really ask for, each time I see him. When I got ready to leave he was applogizing that we couldnt hang out longer and thanking me for coming over. Also I don't think I've ever gotten so many smiles and stares out of him, than I did that night.
I'm contemplating whether I should text him tomorrow just to see how his work stuff turned out or if I should sill keep doing to whole letting him contact me thing.

His way of initiating a meet up lately is always saying things like "I wish you were here right now" or "I want to (whatever it is) with you right now." Over and over until I take it a step farther and mention coming over. Then he'll be like "ok! if you want to 🙂". But if something gets in the way and I can't go see him, suddenly I get tons of "but I want to see you right now" or "this sucks, I wish you were here now" texts and sad faces. Along with giving me ways to come see him anyways, like if I have to be somewhere else he'll be like "can't you just be late!" or "I'll pay for a car to get you back home (we live in a city), I don't mind at all".

Thanks for the replies! I'm going to let him keep contacting me. I did text him today just to see how he was doing with the whole stressful situation with his job (and to show him that I actually care). we talked for a only a short while because he was still at work. Now I'm just going to take a step back again and let him keep coming to me. The other day I made sure to tell him twice that I enjoy visiting him and spending time with him, so hopefully he's keeping that in mind.
