So sorry your marriage is rocky at the moment. Don't give up, even if your spouse decides to live apart for a while. Sometimes you can each work on your own issues & then things just might work out.
Hopefully other efforts will help before it comes to that, like the counseling suggested, either together or individually. A close friend or family member to confide in for support.
Hang in there, this could have been a big blow up that will blow over after things calm down.
Best wishes.
