Should i tell my one night stand?

Not until you are sure. What type of input would you be looking for from him?

I agree with Engineer ...why would you tell him unless you are completely certain?

It's your body, it's your choice. You should only tell him if you are pregnant, and want to keep the baby. Btw, pregnancy kits are very cheap, and accurate, I'd get one as soon as possible.

Hello,
I am completely against in this, she have to tell him all the reality tell me if this is done by her man then have you guys support him? No you don't because you all think that all men are same. I feel sorry for your mentality.

I feel sorry for someone who posts a load of incoherent gibberish.

Plus the baby's already in high school.
