Nice catch. Yeah, once you do find one to care about and provide an extra measure of security which can benefit the two of you - she loses all respect for you and is down the road in a heartbeat.
Leave them to their own devices is what I recommend.
I just discovered my wife is my reward to my meanings toil:
Ecc 9:9 Live happily with the woman you love through all the meaningless days of life that God has given you under the sun. The wife God gives you is your reward for all your earthly toil.
