mikehall – I think it is very healthy for children for their parents to go on dates, not just because it provides a good role model for healthy marriages, but because healthy communication between the spouses aids united parenting.
My wife and I have started working short dates into our schedule, since they can be done more frequently. We take walks outside. Once we went out for breakfast. It may not seem exciting, but the chance to have uninterrupted conversations is priceless.
