Hell no, I would not marry myself. I'd be awful and have expectations. I'd be critical and impatient. I'd bitch and moan that I was not doing my share of the work. I'd criticize myself about my poor skills as a cook and housekeeper. I'd want me to be better with money, to own and know how to use a chain saw, to be able to install another outlet in the bathroom and fix the drippy faucet in the kitchen sink. I'd say things like, "It was nice you finally decided to do the laundry, but couldn't you have taken the few extra minutes to fold it and put it away?" I'd eventually divorce myself.
So what made me think about the prospect of being married to myself? It was Lisa. It's her fault.
