Wake her sleeping ass up and throw her and all her shit out the door. I'd actually have all her shit already out at the curb, off the property. No mercy bro. She had no mercy for you or your feelings. You need to be a cold-hearted bastard to her now and DON'T STOP being one! She will change her tune, I guarantee it.
This reminds me of how you are with your daughter. You SAY you'll do this or that (as punishment) if she causes you trouble or gets in trouble, etc., BUT...you NEVER DO A FUCKING THING!!!
The women in your life all have your number bro. Sorry to say, but you need to find a spine somewhere in that body of yours and stand the fuck up. When you say something, god damn you, MEAN IT. And more...DO IT.
Your wife knows she can treat your pansy pussy whipped ass like this and then tell you to fuck off, that it's your fault she got the strange cock, then go to sleep like a baby in your bed. You're letting her do it.
Also, if you want to kill her, an insulin OD works nicely and leaves no trace. You can shoot it in an inconspicuous place while she sleeps (in your bed). Death is probably too good for her though. Fucking cunt.
You're too "nice" to your women, biteme (this includes your daughter). You know damn well what I'm talking about too. I feel for you bro. I've been there. Had a bitch cheat like that, tried to keep her and give her a second chance, because when I said GTFO, she started bawlin saying she was sorry, blah, blah, whatever. Her ass didn't change, she just got sneakier. Kick this bitch to the curb and divorce her so fast she won't know what hit her. Then go enjoy life and...DON'T EVER GET MARRIED AGAIN!!!!!!!!!!!@@#!QW#$Q
