What are your options when you discover your spouse has been cheating (or you THINK your spouse has been cheating)? Well, I would recommend a cooling off period followed by a marriage counsellor if you still really want to try to patch things up.
What I do not recommend is stalking your wife and then tying a thick rope around her neck. Following up on that, your decision to stab her in the abdomen and arm is also a really bad idea. To cap it off, you may decide to stab yourself in the abdomen as well – again highly not recommended if you want to try to salvage things.
Most likely the outcome will not be good for either of you. Even though you both survived this trial, I do not foresee the marriage recovering. They tend not to work so well when you are in jail for attempted murder.
