I agree with Backroads on this. The big thing is respect.
My husband and I were sealed in the temple almost 7 years ago, but then about 2 years ago he admitted that he wasn't sure that he believed anymore and didn't have a desire to go anymore. So he stopped going, but I didn't stop. Its been hard to go with just my 2 young kids, and not him, but it doesn't need to end the relationship. I've heard several stories of spouses just up and leaving if the other told them they didn't believe anymore. That's not how marriage works. Its not always easy, but if you truly love and respect each other you can keep your relationship strong even with the different beliefs.
Like Backroads said, Sit down and talk to your wife to see if she can truly be supportive of your returning to the church.
