Girls pleaae help

So I've been try to hang with this girl bbn I met this is the second time she canceled on me, she always sends me pictures of her on snap I always tell her shes beautiful I flirt with her, she flirts with me back, I'm just getting tired of it, if she really wanted to hang out I know she would've. She has a little daughter, I have Absolutely nothing against her daughter, I know her daughter comes first. She was with her daughter today. But idk I was just thinking of deleting her number and snapchat and just move on.
