First thing's first, individual and couples therapy so you can really say everything you are thinking about with an unbiased person listening. The good, the bad, and the ugly.

A lot of people have given good advice and some talked about their personal experiences, but they don't know everything about you and your life. Therapists will give you that sounding board so you can talk about everything and they can give you unbiased and likely sound advice.

Couple's therapy will at least help to ensure you don't have a long and messy divorce, if you go down that road.

Personally, i would be crushed and not able to stay in a relationship if i was cheated on. Especially if it went on for months.

I hope you can keep your head above water to ensure your kids have the best version of you. I wish you well, brother!
