Welcome to this board! Mary Frances has already given you good advice about your IRA.
I've been in the stock market since 1959, and I've seen so many ups and downs that I can hardly remember them all. As difficult as it is to do, sitting tight is quite often the best thing to do. Since your DH's employer matches his contributions, that is a good thing, but remember if that business fails, you might lose all of the money in that account too! I would keep that IRA and make contributions to it, if you can. As far as having to pay a fee to maintain that account is concerned, that fee is tax deductible, and in my opinion it is usually worth the money to have them do the bookkeeping for you.
You will lose money on your investment accounts from time to time, but it is a paper loss. You don't really lose anything unless you choose to sell at a loss. I will admit that I am choking over the figures we get each month, because we are already retired. I'm glad that the government is going to let us not have to make the mandatory withdrawals from our IRAs this year. We would be forced to sell a number of things for great losses.
