Saggs, is this a sign of interest or no big deal?

I'm a cap and here's a story:

so my sag and I hooked up two years ago and all of a sudden we started flirting again via emails/internet site. After months of flirting he made a very flirtatious and blunt comment so I responded to it just as flirtatious and bluntly. Finally he decided to visit me after work and I told him I was going to cook for him if he visits me. So he came over and I cooked and then we hooked up again. This time it seemed like he was actually happy to see me. He was attentive, more flirtatious, and responsive to me. When I was seeing him 2 yrs ago, he didn't respond to my text msgs after a few days later or call me. Now he responds to me right away and text'd me within the hour to say "thanks." He never did that before. I just think it's weird...is this guy just being a flirtatious SAG? I didn't thnk anything of the flirting for months, cuz according to this site they are just very flirtatious ppl by nature. Now I just can't stop thinking about the changes.

He's probably just more available now and maybe before he wasn't.

I saw him this morning 🙂 because I had to get something from his location (we are in the same company, different location). He was happy to see me or it seemed like. I didn't chit chat with him long and it seemed like he wanted to.
