What to do?
1 - Stop cheating on your husband. You are taking his right away to informed consent and subjecting him to possible STIs and other diseases. It doesn't matter if you are having sex with him or not. It is deceit and disloyalty. He deserves better than your indifference and hate.
2 - Get a divorce. Your husband deserves to find someone who loves him and not be in a farce of a marriage. You are lying everyday to him by pretending to be invested in your marriage when you are not.
3 - Stop making excuses and giving your reasons as there is no excuse for cheating. It doesn't matter how unhappy you are. You should have ended your marriage before jumping into bed with someone else.
4 - End this before your children or husband find out. It will destroy them and ruin the relationship you have. You have a last chance to be honest. Tell your DH the truth and accept whatever happens and try to rebuild from there.
5 - Get therapy and stop depending on a man for your happiness. He didn't rescue you. He preyed on a lonely married woman and is a predator at best. A good man does not have an affair with a married woman. He has poor morals and is a liar at best. You don't really know him, just what he wants to show you.
6 - Accept that you made a conscious decision to have an affair. It is not just the cheating but all the lies you told you family to do it. You put your affair above what it might do to your husband and children. Stop blaming others and understand the decision to cheat was yours alone. No one forced you to do it.
7 - Accept that your poor choices may have alienated your children and family. You should have thought about your children before you started your affair. The truth will come out and your children are old enough to put two and two together and figure out you were cheating on their father.
8 - Stop playing the victim. You aren't a victim here. Your husband and kids are the only casualties here of your destructive choices. You are not a martyr and it is disingenuous to act like you had no choice in this.
