Wrong or right, I'm on a path to cheat on my wife
That sounds like a rocky road.
I don't think she's paying enough attention to me and we are growing apart.
In a relationship it is expected to not cheat on your partner.  You should make an effort to pay more attention to her and save your relationship.
I'm sick of her psycho bullshit.
Have you considered couples counseling? If she's having psychological issues that may not be enough, but it's a start. Having an affair will do nothing to solve your problems; it can only make them worse.
