How not to be to flirty?

Ok you told him so anything you do now is just adding to your relationship until one of you make the move to turn it into more. Text him how ever many times feels right (If you text him and he doesn't respond don't continue blowing him up). Conversations have lives of there own and just let it go naturally don't over think it. Yes you can be flirty, just be playful. Have fun with him but make sure you word things right because you can't use tone(tone of your voice) in writing. What about talking to him on the phone? Or ask him out- go to the movies, your still at friend stage so it's not weird for you to ask him to do something. This is awesome that your friends 1st and you already know you have a great relationship and who he is as a person. You'll know when the time is right to become more- it will happen just give it time or talk to him. Take care hun-have fun!
