I don't think self degradation is the way to go.

Ok you were super chatty in inappropriate ways with women, on the internet.

Certainly, with being married that's not a symbol of being a quality husband.

But slow down just a minute.

You're not her first marriage, I presume? There's a child involved that's not your biologically?

How did this Tinder discovery transpire? Pure guilt? Or did your privacy become violated? Certainly the Tinder crosses boundaries but the answer to this question paints a picture of what's going on in the marriage. What led you astray, so soon?

Relaying her marital details in running to her parents at every corner is most curious, while you are without anyone actively giving you moral support in your corner.

Is there a lot of push and pull in your marriage?

Why is your self esteem so low? Why are you as insecure to paint her in your mind like she's beyond any flaw? That she couldn't sort this out with you first as adult to adult and not scream marriage counseling first is curious. Is it not?
