Dating a Sagg

So I (F 24) am currently dating a Sagittarius (M 30)... The vibe and the sex are * chefs kiss *. But he currently left me on read for 2 weeks and opened the chat with 'sorry, I was off the grid. I needed some time to focus on myself.'

I know that a working person needs time for himself. But we are not in a relationship, so he's a free man. The thing is that he is genuinely interested in me and asks me a lot about my life, but 'forgets' to respond, it seems... IDK

Is it worth it to see where it goes? Or are sagittarius known tot use people for their emotional needs?
