Did anyone have a rock solid marriage before baby and are struggling now? My husband and I have been together for 8 years, married 3. Great relationship, fought once in a blue moon. My kiddo is now 16 months and it seems like all we do is bicker. Little stuff, big stuff..... it's wearing both of us down tremendously. I've thought about counseling. Anyone is the same sad and lonely boat?
