Affair found out - help

Hi ladies

I know I’ll get a lot of stick for this, but we have all made mistakes.

Long story short

I was seeing this guy from work for 6 months and he told me he was married, I still carried on seeing him as I’m in love with him.

Today 13 months later his Mrs found our receipts from last weekend away for my birthday and he is waiting for her to return to see where there relationship goes.

What do I do?? Do I help him pick him up and take him in or let him sort his own mess?! I want to help him but it will of course have impacts on my life friends and family such a massive descision to make In the next couple of hours
