what happens to the marriage?
 

I would appreciate an honest response
After few attempts, my wife has met few black lovers.Although, it was a fantasy that I initiated and worked on to start with, she was into an open relationship as well.
My concern is that although we have been married for 15 years, I feel that she has changed dramatically. I am not the person she depends on or share her thoughts with. Actually I feel that she has no respect for my opinion any more.
So my question is this the expected behavior of the wife towards her husband although opening up the relation was intented to keep her satisfied

In my experience there are other problems in the relationship.
 

Cucking and competition creates a sense of urgency around keeping your woman satisfied overall.

We get lazy sometimes, and other partners are going to try to get your woman . She'll be snatched from you if you stop trying.

Stop trying? What's left to do?

It sounds like you need to talk to her.

I wouldn't lend out a GF to other men if I really wanted to keep her.

But any woman I would want to keep, would have to be lent out, so I just have to be prepared to lose someone. They usually come back though.

I think being married is different from GF in many ways. So the question is what to do ? I didn't think about it . I didn't expect that the permission to date others would jeopardise our relation.

Women are emotion driven. I believe you can still get her back if she loved you before.

You can't have an open relationship if you want to keep her.

Maybe talk to her about how you both met. She will remember, and smile at the very least. Try to regain what was lost. She wanted you at some point in the past, and that's still in you. You can be the same man, just older.

If you want to keep her, it's going to be work. You will do it if you still want her.

It's a shame that you don't describe how much she has changed.
Sometimes she may develop feelings for her bf/lover

My wife and I have been married for 52 years (first and only marriage for both of us). Prior to our wedding day, we made a joint commitment to have our marriage follow a hot wife/cuckold husband lifestyle. Sex is solely between my wife and her Black boyfriends for the purposes of giving her carnal pleasure and breeding her. Love is strictly between the two of us as husband and wife (soulmates). We are always honest and forthcoming with each other. We have had disagreements, but we have a joint commitment to never retire for the night until disagreements are resolved (usually through compromise). We are both sexually submissive to Black men, but neither of us will be owned by or a slave to a Black man. The same applies to each of us to the other.

We understand that the telling of our good fortune comes too late for those writers who face the collapse of their marriages. However, we are always optimistic that they may find a way to remake those marriages. Bill & Jan

She had dramatic change. new sexy clothes, new hair style and color and definitely feels more empowered.

It's true that women are very emotional, my wife has bonded with her black lovers but I am her #1 and her soul mate! We are poly so we believe that men & women can love more that one person!
This life-style is great for us but it's not for everyone! I think you should talk to your wife about how you feel!
