Need advice on WAW with OM

[svejk]

Would it be a mistake to ask my wife something like this:

"I know that you are still seeing the OM. We agreed to a 1 month no contact period because you said you needed space to figure things out. However I cannot stand by and wait for you while you are carrying on a relationship with the OM. If you insist on continuing with the OM then I will end our relationship immediately. I don't want to give ultimatums, but for my own sanity I have to. If you still want the space to figure things out about our relationship I am still willing to give you the space as long as you are not seeing the OM. If you are unwilling or unable to end it with the OM then please be honest with me so I can go on with my life."

Thanks in advance for any help,
Svejk
