^ very valid points and I agree
@Glassguy. In my experience though if the chick is interested in you she won't see any of that as being desperate or losing frame. The text could've been without the 'when you have *some* time' though. My go to text is always a variation of "Sounds good, let me know what days/times work for you". This forces her to come up with a concrete day/time and you're not asking 'if' she'll go out with you you're asking 'when' she'll go out with you. If she doesn't respond, just have to have the IDGAF attitude and move on to someone who is interested.
