How many "I'm busy" to your date request before you give up on a girl?

If she's busy but doesn't come up with a counter offer :"I'm busy this weekend, but how about Wednesday?" she's very probably not interested and just trying to let you down easy.

It depends on the context, should could genuinely be busy like we all are with work etc life but if she doesn’t suggest another day or date then it’s probably likely she doesn’t like you.

One if it's the first time you ask
