I caught my husband having sex with my best friend

I left work early cause I didn't feel well. And I caught my husband doing my best friend (now my pregnant ex best friend). Here's a surprise he drunk again. We also have 3 week son whos very needy. Should I leave him?

you have my permission to trash them (even tho I do it three times a day lol)
