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

This week's Happytoys enthusiast leads a life many would envy, yet she has a problem

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

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

Should she follow her feelings and turn her life upside down for nothing? Or should she stay in a relationship that she realizes may not truly make her happy?

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

The problem…

I am a 54-year-old woman who has been reasonably 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 a nice vacation 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, actually, I have nothing to complain about and I know I should be grateful for the happiness I have.

Yet, deep down, I am still restless because I am 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 that it is him in bed with me.

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

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

I realize I am old enough to know better, and it would destroy many people if we ran off together."

What advice would you give this week's reader?

Simone's advice

Since you have 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 have been with your husband for a long time, and perhaps your life has become a bit predictable and boring. It's understandable that you fantasize about someone else, but putting that fantasy into practice would be very different and might not yield the desired result.

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

On the other hand, imagine he feels the same way you do, and you decide to take the plunge. It is very possible that your relationship would not survive if you were together every day, and that you would regret the pain you caused not only others, but also yourself.

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

Remember that this man is a friend of your husband, and his loyalty might lie there. If he tells your husband what you told him, you will have a lot of explaining to do.

The other, and perhaps wiser, option is to work on your marriage. It seems that marriage counseling might be necessary; look online for options in your area.
