I can remember feeling that way about a year ago. I was very worried about our marriage. Here are some things that have helped us...
1. Find some time for YOU...a yoga class, a pedicure, whatever would give you even an hour to focus on absolutely nothing else.
2. Mandatory date night - have it scheduled as a must-do. Make it the same every month. Our's is every 3rd Saturday night. We have the babysitter all lined up. It's too easy for months to pass without it.
3. Consider going to a couple's weekend or a couple's counselor to help remind yourselves why you are together and that there still is love there. Just hearing it come out of our own mouths really helped us rebond. The scariest thought for me was life without him around and how that would change everything to a much worse situation.
4. Fake it until you make it. Plan a kiss at the door when you first see each other at night. Make dinner time a "how was your day" time for the family - no tv or anything else.
5. Plan a vacation! Big or small, kids or no kids - you will be glad you did. It has really helped us.
6. Consider saying "no" to anymore responsibilities or cutting out some of the ones you already have yourself wrapped up into. Super moms are only super if they can take care of themselves, too!
I hope this helps. These changes have really made a difference at our house. Good luck and God Bless.
