Best way to make her realize she needs me?

can anyone tell me what the best way is (if there is a way) to make a girl realise how much she needs you???

I don't know if this is actually possible, you may want to try just being there and listening, or go on vacation and don't contact her for a week and see what happens. It really depends on your relationship with the person and if you are just friends or have been dating for a while.

I agree wtih mshell0809
for a period of time be there for here. talk to her.
then after that, don't contact her, wait for her to contact you.
it workss.
well I realized how much I needed him when he did that to me.

Good luck!
