Is it also normal to feel you need to be more secretive about things? Like privating socials to keep certain people from seeing what you might be up to?

Asking because this is my situation currently with someone I was intimate with before she took space a few months ago to work through and heal from her depression and a divorce she had a year ago. And I'm just not sure if these are symptoms of depression or if she just wants nothing, or little to do with me. We have talked sparsely here and there for the past month, but it takes her weeks to respond. A part of me feels like I should take that as a hint and move on, but she tells me really nice things too, tells me I mean a lot to her, so I've just felt really confused by all the mixed signals. I feel immature in feeling like she's trying to work things out with her ex, or met someone else and is just keeping me on a leash and just won't, or doesn't know how to tell me, but I don't know depression and what it can do or how it makes people act.

So I was just curious if this kind of thing is normal, and what it is I can do for someone in this situation? Is it best to leave her alone and let her respond when she's comfortable? Do I check in? Does it ever feel smothering to be checked in on or reached out to? How about if I tell her how I feel, what I've been worried about? Do I just keep that to myself or express it to her? I just don't know what to do.

Thank you for any replies
