Delete her number as well? I do and don't depending on how interested I was in the woman. If I was really interested than I delete the number because it 'saves' me from maybe contacting her again when there's no point but I won't look at the number twice after I've nexted a woman who I was only interested in for a one nighter.
I know deleting the number shows lack of self control on my part and destroys the chance of hitting the woman up down the line but it works for me. A few times I had deleted the girl's number only for them to contact me a month or two or several months down the track. I didn't know who it was and they asked if I had deleted their number. Easy reply is my phone broke got a new one had to start contact list from scratch.
