I'm starting to accept that my marriage is one of those "perfect on the outside" marriages but if anybody knew the real story

My friend / neighbor even comments on how lucky I am to have DH.
Having grown up reading Ann Landers, I keep asking myself "better off with him or without him?" With, unlike my ex - he isn't abusive, he has a job, we do have things in common, goodwith the kids, but his responsibilities begin and end with his job. Meaning, if I don't do it then it doesn't get done, except for mowing the lawn, I'm not allowed to touch the mower. Everything else is my responsibility.
And yes I've talked to him, not yelled, screamed, cried or threatened, actually t-a-l-k-e-d. He knows how I feel and I know how he feels, nothing changes.
And no, it wasn't always this way. He's flat out said to me that he's just too busy to have to do anything around the house.
So, yeah, just because every marriage looks happy doesn't mean it is.
