You don’t want whole life. Buy term life insurance. It’s cheaper, and if you invest the difference in the premium between term and whole, you will be ahead later in life than if you just did whole life.
Do you have any professional groups that you belong to that may offer a group term life policy, that may be cheaper than just buying as a member of the general population?
Do you really need life insurance? The purpose of life insurance is to replace the wages of the main bread-winner. If both you and your spouse-to-be are working and making a livable wage each, there’s really no need for life insurance until or unless there are kids involved.
Also, you only need to insure the main bread-winner in a couple. There’s really no need to insure a non-working (or only lightly earning) spouse. As above, this changes if there are children involved.
