Re: Affairs (Physical and emotional)
I don't exactly understand where you are coming from. Tolerating multiple affairs, whatever the rationale, is beyond me so I feel that I may not be able to offer useful advice.
Where I can offer input is to ask if you are a SAHM because you want to be, or because you can't make enough money after daycare to justify working? Do you have a degree?
It sounds like you need a career. Not just to provide an income, but just as much to give you some perspective on your own value and what else there is in the world, and give something else to focus on.
