Simone, from Happytoys.nl, regularly talks to Happytoys enthusiasts.

This week's Happytoys lover has a life that many would envy, and yet she has a problem

At 54, she enjoys a long and happy marriage, a close bond with her son and three beautiful grandchildren.

But behind closed doors she feels unfulfilled and harbours a crush on someone who, if discovered, would certainly cause drama.

Should she follow her feelings and completely change her life for nothing? Or should she stay in a relationship she realizes might not truly make her happy?

Read our expert's advice below, but before you go, check out last week's dilemma, from a reader pregnant with her selfish ex's baby.

The problem…

I'm a 54-year-old woman who has been relatively happily married for 28 years, with an adult son and three wonderful grandchildren. I live in a detached house in an affluent neighborhood, go on nice vacations a few times a year, drive an expensive car, and have a good social life.

And even after all this time together, my husband and I still have an active sex life.

So basically I have nothing to complain about and I know I should be grateful for the luck I have.

Yet, deep down, I'm still uneasy because I'm not with the man of my dreams. In fact, when my husband makes love to me, I always think of that other man and imagine it's him in bed with me.

This man is a good friend of my husband's, and I've known him for over 20 years. He's never met the right woman, and perhaps that's why he's tried to stay young and attractive—unlike my husband, who has allowed himself to become fat and unattractive over the years.

We've always been good friends, and I've mended his broken heart more than once. We've never kissed (except in my imagination), and my husband doesn't seem to realize how close we are.

I realize I'm old enough to know better, and it would destroy a lot of people if we ran off together."

What advice would you give this week's reader?

Simone's advice

Since you've never kissed this man, talking about running away together might be a bit premature. Take a step back and consider the reality of your situation before proceeding.

You've been with your husband for a long time, and perhaps your life has become a bit predictable and boring. Fantasizing about someone else is understandable, but putting that fantasy into practice would be a completely different matter and might not yield the desired results.

I can't help but think that if you were meant to be together, your dream partner would have already made a move; telling him how you truly feel would be a huge risk, and you might even lose a special friendship.

On the other hand, imagine that he feels the same way you do, and you decide to take the plunge. It's entirely possible that your relationship wouldn't survive if you were together every day, and that you'd regret the pain you'd caused not only others but yourself as well.

As you rightly say, you have a lot to be thankful for, so please think very carefully before risking your beautiful life.

Remember, this man is your husband's friend, and that's probably where his loyalty lies. If he tells your husband what you've told him, you'll have a lot of explaining to do.

The other, and perhaps wiser, option is to work on your marriage. It seems like couples therapy might be necessary; search online for options in your area.
