I want to share with you something powerful to do in prayer, also, in addition to all these other wonderful suggestions. On your marital issue: go through the Bible and choose key scriptures that speak God's Word & promises re: marriage & love. Write them on index cards, & pray them together with your husband every night. You will be amazed at the result.
A living example: my husband & I did this re: our infertility (in our eighth year of THAT barren wilderness) and we told no one; it was our private thing with God. Hannah's story/prayers comprised the majority of our index cards, and as you know her son was named "Samuel," which means "God has heard (my prayer)". Our adopted son came to us after praying this scripture-promise prayer for many, many months. And he came to us with a beautiful confirmation from God: his birth mother named him, "Samuel" on the birth certificate..."God has heard."
