Being deceived by WAW, in need of some coaching

[skr4luv]

I'm also planning to confront her tonite or tomorrow night about her continous texting and my suspicioun that she still sees him during the day.

My inention is to make clear that I don't want to live in a marriage where she's not 100% faithful.

Can someone advice me of an effective way of saying that without sounding needy and controlling, but firm and setting a clear boundary?

I'm thinking of something like:
"Look you obviously haven't stopped texting each other. And I believe you're still seeing him. There's no way of working it out between us if you keep him around. When you're lying to me, your lying to us and our future as a family. If you can't be 100% faithful then we should start discussing how we're going to separate...."
