I used to work for life insurance companies. Here's what I can tell you.
How healthy are you? Generally, at your age, you will have to submit to a health exam if you want to be underwrittem for insurance. Minor things may be OK, but if you have diabetes, a missing organ, asthma/COPD or similar chronic conditions, they may decline coverage.
Whole life insurance is usually more expensive. They will hold some of the premium payments as "cash value" but that cash value can shrink as you get older, because they assess more administrative costs as you get older. Generally, it's better to put that money into savings vs letting the insurer have a free loan where they are not paying you interest.
Term life insurance is always the cheapest in terms of cost, and can be continued from term to term, but again, it may require new health exams to continue from one term to another.
The easiest way to get a life insurance policy is through one's employer. Those usually waive underwriting, which is a bonus, but not all of them will be "portable" - meaning, you can continue it even if you leave your employer.
If you had a larger amount of money to invest, you could consider an annuity, where you name Papi as the beneficiary. (Not to be mean but nothing you said suggested you were working with large sums.)
Speaking of beneficiaries, it's also important if you have a 401K or pension plan to name him as beneficiary there, too.
At 48, it's probably time to see a financial planner and do a will/trust if you do not have one, as well as getting POA's for healthcare and financial down on paper. (We're actually behind in doing it ourselves, but my husband's work gave us a benefit this year of free legal assistance.)
