You're not a candidate for Discernment Counseling.
Discernment Counseling is for couples where there has been some form of stated expectation to stay together for life, with marriage, a commitment, or children, and this commitment is well known publicly.
Discernment counseling is not a good fit if:
a) both of you are leaning out of the marriage, or
b) the leaning out spouse is fully on board with trying couples therapy.
Individual therapy can be very helpful to get a third party perspective on your role and your choices now to change the fate of the relationship.
