<human>: Can you condense the text into three sentences or less?

We were together for about a month and a half and didn't really end on the best terms. Her birthday is in a couple weeks and by then it will have been **3** months since I've seen her. She wished me a happy birthday during this time. Up until a week ago, all we'd do is text(fairly often). She'd always have a reason for not wanting to hang out with me when I'd ask. So about a week ago, I gave up. Haven't exchanged texts since. It's like she wanted me to keep trying, still does according to some twitter posts. Everything literally ended overnight with us, no real explanation, just left me hanging. I still feel that there's something there. 

If we dont talk or text before her birthday, should I wish her a happy birthday? I know my question is kind of lame, but because of the circumstances I don't want initiate the conversation.
<bot>: Ex shows signs of wanting me to keep trying, havent seen her in almost 3 months, texted in 1 week, and her birthday is in two weeks.
