Don't tell him your dating. Just do it. Word travels. Date can just be a night out with a single friend of the opposite sex.

And if he asks if your dating. Don't say yes. Deploy WAS fog.
State " You wanted me to be happy, right? Well I am being happy"
Leave it at that.

Flowers always make people better, happier, and more helpful; they are sunshine, food and medicine for the soul.
unconditional love is awesome!
