Steven,
You give a lot of good, sensible advice on this site, and I usually agree with you. However, we might just have to agree to disagree on this one.
The OP did not say that he was male and his future spouse is female.
We don't know what they both earn or whether they are already living together. I will admit that I am reacting a little to the tone that a husband should look after his wife, which may be unfair of me, but its not the 1950s.
I stand by my statement that both spouses should consider the need for life insurance in the context of their overall financial situation and their future needs, which dont necessarily change one day because they are married,
