Is it wise to check in?

I've been debating whether to ask how he's been doing after three months of no contact. I'm not expecting to rekindle or to get back together at all, I just wanted to know what he's been up to and give a little life update. What’s holding me back is I don't know if he views this as a burden, and he doesn't want to receive messages from me ever again because he doesn't want to be disturbed. I guess what I'm trying to say is I have a hard time balancing what I want and what he might want. Obviously, if it's going to be bad for both of us, I won't do it, and reaching out to me feels harmless because I'm not asking for more. Could someone tell me if you are the dumper or if you didn't tune in as much as the other person, how would you feel being reached out to?
