Lots of things to deal with in second marriages. Have you been to counseling first of all? Are you both on a second marriage and comparing your problems to your last marriage? Are you trying to handle problems the same way? See what I mean? The list is endless and the problems aren't usually the real issue, but a result of something else.
If you are bored with one another you married too soon, and need to begin as new lovers who are just beginning the dating stage without sex. This doesn't mean moving out or not sleeping in the same room, but on a date.
You have to like one another before you can understand that love isn't an emotion but a commitment.
When your spouse does a kindness for you it is an outward demonstration of their feelings. Going to work to pay the bills, talking until 3 am until a problem is calmed, learning that submitting to one another isn't weakness is love.
What attracted you to one another in the first place? If you are bored, you are boring not just to one another but to others. Try doing new things and going to places of different interest without spending money. You'll be surprised how your conversations will change along with being bored with one another.
