Search Results: not able to see boyfriend

I was working with this really nice lady, at least so I thought, a few years ago and we hit things off and had chemistry together. I was in the middle of a break up and she said she was amazed with how much love and care I was giving my ex.
We didn't date because she had a boyfriend and a son, but by the end of the summer, they had split and we're in custody battles.
So we started talking and I asked her out. We were originally gonna see mission Impossible for the first date, but she never responded the day of the date.
She said something with her ex came up and she wasn't able to respond.
She said a few weeks later she was talking with someone else and appreciated my interest.
About a month later she started talking to me again, and we arranged a dinner date, but her sister wanted to come and she said they'd all meet me at the place. They didn't show up, and I messaged her asking where she was and she said they weren't ready like a half hour later. I asked why I couldn't get a heads up, and she said she was busy. I got mad and asked her what her intentions were and she said she couldn't answer me at that moment.
After a week, I blocked her.

Did I do the right thing?
Was I even gonna get a fair try?
