Time To Move On?

We have been through thick and thin. I believe in working out the worst in situations; especially if we are married. I have been there through all his falls (health situations, his grandfather passing, and other numerous events). We hve always come back on our feet. This time it is us and I cannot be there to help. We have discussed marriage counseling. I believe it would help but he feels one person can't help a couple in distress. I think separating may help but of course hope for the best. I feel our relationship is just going through a rough patch and we need to mend the problems and not run away from them.
