Which is more appropriate? I think taking her number is much better as it gives you more planning power rather than waiting for someone to text you.

All along I've been taking numbers for ladies with good success but recently I followed an advice here and decided to try giving out my number instead and that has led me to lose a very cute girl.

You know women can be very undecided, sometimes she may even like you but swear to never text you (like I have been reading women saying out from other platforms)
