Search Results: really interested, just being nice

I was talking with a really nice girl for a while, and we had an interest in dating and being in a relationship. When she came down from school, we went out and she told me afterwards that she thought she was ready to date again, but she wasn't over her ex.
We had a few intense conversations about it, but she said she doesn't know how long it will be until she's ready.
We haven't talked since. The last time we spoke it was very brief. Do I follow up with her at some point or am I supposed to wait for her? Also, it's my birthday this week, if she doesn't acknowledge that, does that mean she's not interested or doesn't care?

I started reconnecting with this girl back in July 2018. She made it clear that she was working through some problems, but that she wanted to talk and be in touch with me, even though she was leaving the country. Life hadn't worked out the way she wanted, but she seemed interested, basically, in including me on whatever her next step in life was. She had made plans to visit me later that fall... unfortunately, none of this has worked out... she is still working through her problems, and seldom communicating to me. Even though I write her fairly often, she usually reads the messages quickly but doesn't typically respond. When she does respond, our conversations are quite intimate, but it's infrequent.

In months passed, this was okay with me, because I knew she was working through depression and other issues (and the timing of things in my life was such that investing in her was convenient, and just worked). I have spoken to several of her friends, and they have all been supportive of me and her, saying that she would make a great girlfriend. I always hear is "give her a chance." Giving her a chance was great before, but I have a life to live...

I feel like I've given her a chance, and I'm just not seeing any traction. A relationship with her would be amazing, because she's everything I've ever wanted in a woman. The only thing that scares me about being in a relationship with her, is that I have no idea if something like this will happen again. I need someone who can handle the adversity of life without curling up into a ball, just because life poked her with a stick.

She wrote a really nice public facebook post about how she was feeling better as the new year started, but she hasn't been messaging me. It's my birthday in a week, and I have chosen to look at how she wishes me a happy birthday to see if I'm wasting my time.

I also wanted to get some other people's opinions though... what do you think? Is this all part of giving her chance, or should I bail?
