I believe I said that a "disadvantage" is that nothing you do is for yourself. You should let that sink in. Worrying about time, money or freesom is all about yourself.I noticed that no one has mentioned any major cons (that I remember), such as money, time, or - freedom. Are you just not mentioning them, or are they not an issue for you? and if not, then why not?
You say you're "disabled." If it's a genetic defect serious enough to worry about your progeny, perhaps you shouldn't marry. Being single offers a tremendous advantage in the work of the Gospel. If you have the gift of celibacy, if you find you can contain your desires, you would do well to remain unmarried. But if you're finding that you can't contain your desires, then marriage offers a tremendous advantage—though its not the best reason to be seeking a mate.
