Welcome to this forum, Calvinia. Nice to meet you.
I’m so sorry to hear that you’re facing problems in your marriage. Have you considered talking to a couple counselor? A caring professional might be able to give you some solid guidance. I just said a prayer for you and your spouse, asking God to bring healing to your marriage and to provide the wisdom and help you need at this time. May you rest in the assurance the psalmist expressed when he wrote: “In the day of trouble I shall call upon Thee, for Thou wilt answer me” (Psalm 86:7). Grace and peace to you.
