don't know how I feel about my husband anymore!

I'm really down! I love my husband so much but I feel like I'm so bored. We don't do anything together anymore and I have tried and tried again to spice up our relationship but it just goes and dies again we both love eachother so much but I just can't live with having a roommate. Has anyone ever felt this? (We have been married 5years and have two kids) whenever I sugest going on a date and I take the kids to a family memeber he just wants to stay home and watch tv. Seriously?!? I don't know what to do anymore
