My husband is not an outgoing person. He doesn't like to go swimming or camping, or go to the park and those sorts of things. He doesn't like to do family parties, either. I love to take my kids out and do these kids of things with them, and they have so much fun. I think it's really important for him to be there too, at least some times. Otherwise he's a really great dad. How can I convince him to be more a part of our family outings?
