Then save your money. If there's another guy in her radar she'll just use counseling to "try to prove" that the marriage is unsaveable.

Her admitting there's another guy she likes is a line crossed. I recommend if that's the case for you to drop the rope and go dark. Is she still living with you? If so consider separate housing arrangements.

I know she left returned, and is now flipping on you again. She appearantly can't still make the choice to put whatever anger she has behind and focus on truly piecing. She is still WAW, and in my opinion will probably stay WAW until something radically changes.

That changing factor needs to be you, personally I think you need to talk to her and let her know that her having feelings for someone else is unacceptable, and she needs to decide if she will pick him over you. Yes it is an ultimatum, so you have to be 100% ready for her response.

Judging by your previous posts it seems you are getting tired of this, and I don't blame you.
