I'll admit it's hard to be romantic when you've been married a long time and have kids. I mean your spouse becomes more like a partner in a business sometimes than your romantic lover.
Running the household, dealing with teachers and homework, finances, housework, taking kids to sporting events, career issues, etc. Plus our occasional spats.
It's amazing that we do sometimes find time to act like a romantic couple. Usually happens when we go out, which we try to make happen at least once a week. Those usually end in good love-making session too.
