PLEASE HELP!! Do depressed partners usually come back?

I've been dating this really awesome girl for about 2 years now. She's a little on the clingy side, but she's cute, quirky, and was everything I was looking for in a woman. She's also full of energy, something I never really was but she's made me step out of my comfort zone and I liked it! However, things took a complete 180 recently. Almost 2 1/2 months ago, completely out of the blue, she broke up with me because she felt as if she was "dragging me down". I had no idea what prompted this until I literally had to fish it out of her that she had depression. She's suffered from it in the past. She said she wants some time and space for herself and it wouldn't be fair (to me) if I was included. Not knowing everything it entailed, I've been doing research on depression and leaving someone alone is the absolute worst thing you can do. But, I told her I respect her wishes and I'd leave her alone. She said she doesn't want to cut me out entirely but felt she couldn't be in a relationship "at the moment".

We haven't spoken since. I sent her a text a week after the breakup reminding her I was still there for her. I've been pretty good with the "No-Contact Rule".

Get this though, we are still friends on social media and she is constantly online (Facebook, Snapchat, Twitter, Instagram), liking posts about "how good it is being single" and such. I see her post pics of herself being happy with other guys commenting on them and she responds to them instantly. So much for "not cutting me out entirely" right? I want to be a nice guy, and yes I know I know, I should be the one to unfriend her on social media because at this point we aren't even friends. I know all I'm doing is hurting myself even more, but I'm stuck.

Do depressed partners usually come back? Or have I just been getting played this whole time? Is it even worth it? She's pretty religious so I don't think she has the morals to cheat or hurt me, but who really knows in this day and age right?
