No, you shouldn’t force anyone to do anything.
However, with much love and grace, hopefully that she will eventually see, you can suggest, encourage her into counseling.
Do you have a counselor for her? If not, maybe she just can’t get it all together to find one herself.
Is she aware that she is suffering? Or is she blaming everything on you?
Print off information on the net for her to read. Explain to her that you do not like to see her suffering, to see your marriage suffering. Maybe even go to counseling together, again, so she doesn’t feel so threatened.
For some people, they have to hit rock bottom, for some people, kind words and gentleness works the best.
I don’t know your wife’s temperment. I don’t even know your temperment, however, I always suggest using grace first instead of force.
I will pray for you.
This is never easy to deal with.
