I can't ever forgive infidelity but is it too late to start over at age 42?

He broke my only single exception that I can't ever forgive nor work out. I haven't really confronted him yet because our twin sons' 19th b-day is this Sunday.

I've discovered his infidelity last week (even have his own voice recorded where he has a private conversation with his friend and admits to it) and found out it has been going for nearly 8 months. I really hate to break up our family, never wanted to but it's like he gave no choice. I can't forgive that. Cheating has always been a deal-breaker for me.

Taking him back would be an insult for me as a woman and setting a bad example for our sons. I can't tolerate it. I'm waiting until Sunday is over. I'm not even going to yell nor make a scene; no need for if he literally threw away 22 years of love (2 years of boyfriend and girlfriend and 20 years married) as if it meant nothing. I just want to be done with him as quickly as possible and not see him again.

Is it too late to start over at age 42 once I'm done with all this process?

Anyone suggesting to try to find out the reasons why he had an affair and consider if it can be worked out, I'm not going to bother with that. The moment to work things out was before he decided to cheat. Now there is nothing to work things out. He refused to work things out when he cheated.

Even worse. In addition to his infidelity, he got his mistress pregnant too. I've just set up an appointment with a lawyer and will be divorcing him ASAP.
