Even more than cheating

A girl reached out to me on Instagram. She told me all the truth and even sent me screenshots. My husband was sexting her first a few days, about a week.

He’s sexted before. About 4-5 times. One of the times he kissed the girl and that’s all I know.

We been married 5 years and together for 10 years. We have a 16 month old baby, our first very much planned baby.

What is driving me insane even more is that he sent a picture of our daughter to this girl and told her our daughter is his niece!!!!

I can’t get over the fact he did this and I’ve been trying to wrap my head around it.

Side note - I plan on leaving him, getting legally separated to begin with. I don’t think I can forgive him for this.
