Cuck?

Long story short,

​

My GF and I have been together for 12 years. We have a 5 year old son. Yesterday she told me that she doesn't like to have sex with me because there is nothing new. We have done it all..

She finished her outflow by saying that if she was with another man it would be fucking amazing in terms of sex because it would be a new body for her to explore. I asked her how does she knows this, she told me she knows herself..

​

She says emotionally we are fine, she loves me but that the passion or chemistry is gone and there is nothing that I can do that would make her horny.

​

I am well built, athletic, educated, i put money in the house, i do chores and task sharing, help a lot with our son..

I have no idea of what is going on..

​

Help please.
