Search Results: ex really upsetting me

I started talking with this really nice girl back in October, and we seemingly clicked pretty well. We both recently got out of long term relationships where our ex really hurt us, but it seemed like a good match.
She was two hours away for school, but we still talked everyday. She expressed interest in dating and spending most of her winter break together, and if all went well, I'd meet her parents at the end of the break.
But on our first real date, she said she thought she was ready to date again, and asked for more time, and she was very apologetic, but we still had a few hard conversations about the situation because I was super bummed and upset.
Anyway, we've only talked a handful of times since and she said before Valentine's day she still wasn't ready, but I still wished her a happy Valentine's day and said I hoped all was well and I understand she's not ready, and I wanted to make sure she was doing ok.
The other day, she got a bunch of snow, and I was just trying to be friendly and talk to her about it since she loves it. But she still didn't say much, and I've delayed answering because the way she's responded lately has made me just more annoyed with the situation. But she still responds, although she doesn't make the conversation engaging. I understand she's still hurt by her ex and trying to move on. She said she just never got the closure she wanted.
At this point do I just give up? I haven't even read or seen her last message back to me...
