Was she aware of you being a cheater before you got married?
Have you thought about counseling? Not marriage counseling but just the regular kind. It might put some things into perspective for you
Bullshyt, you can love someone and still cheat.
Men cheat in their mind 24/7.
Having sex with a jump off doesn't change/lessen the feelings for your wife.
Honestly yall both sharing each other. If your wife was still alone then chances are she would be bat shyt crazy and wreaking all kinds of havoc in your life. She seems eerily calm for a woman whose man possibly bought home a few case of the itchies. She is having sex with someone else, and she, like yourself, still has strong feelings for you...but she is still getting scooped out.
I think this will eventually fade itself out...she will eventually stop calling you and you will eventually....well I don't know. However...unless you guys agree to an open marriage then its simply not going to work.
