You need to get a smarter husband. Or one who shuts up and stays out of your way. Or at least maybe your own investing account.Take a deep breath and jump back in - that is the only way to get back in the game.
We made the same mistake on Apple. We owned 2 iPods early 2000s and loved them. When iPhone cane out in 2007, we both purchased around thanksgiving. That was such a superior product to anything out there that we purchased 300 shares of AAPL. Well just over an year later the price had doubled and my husband insisted that there was no further growth and we sold. Then every time I wanted to buy again, he felt it was too expensive- so we never got back in. Think of what 300 shares from 2007 would be worth today.
I decided to start managing my own retirement investments myself in 2013 - the very first stock I purchased was AAPL! It has done very well since then too.
Better late than never I say.
