yes it is good, but u need to respect what she says too. maybe ask her if there is a way she can make time, or if she would consider making time in the future. allow yourself to pursue her, without getting in her way.
If she's showing any signs of interest, persist... lightly (e. g., text her something funny or just to say hi, twice a week WITHOUT asking her out, then when she seems more talkative invite her out to something specific).
If she doesn't engage you back in any way, being persistent = stalking. So, try a little, but don't put your dating life on hold for her.
What usually happens is that you'll persist for a while, she won't respond, then the exact moment you meet a new girl you really like, THAT'S when she'll finally want you.
Why is this? Because, the universe has a sense of humor :)
Please don't bug the shit out of the poor girl. It seriously will only serve to do one thing. Make you look needy & desperate. Keep it casual and interesting, there's no "magic" way to make her want to date you all of a sudden. Talk to her, respect that she may be too busy to reply (you'd be surprised by how many women genuinely are) and keep it flirty so you don't get friend zoned lol. Good luck man.
Ps. If you really want to date, then don't wait for any one person, the world's your oyster ;)
