I don't think it's selfish; it sounds like you've considered the options and effectively decided to self-insure, and that you can afford to do so. I assume that if one of you were unable to work due to illness or injury, or if you had other dependants (ie kids), that you'd revisit whether you need life insurance or not. I think that's all entirely reasonable.
what if you two were both in a car accidnt, you die, the mrs ends up in a wheel chair, cant work ever again??? What happens then?? Sells up pockets 100K and moves in with her parents on the disability pension of 18K per annum....................nice position to be in
