Does this really have to be the end?
Can you love and accept him as he is?
As a poly person I find the amount of monogamous people who are willing to write off years of otherwise happy marriage because he looked at dating profiles pretty astounding
I thought the point of getting married was to ensure a more secure relationship that couldn’t be pulled apart by the waves of life.
Only you can decide what matters to you in a relationship.
None of the usual rules have to apply.
It’s about you and your husband finding the best ways to get your emotional and physical needs met.
Sometimes with each other or sometimes being giving each other space to nurture other relationships with friends.
Personally as long as he is using protection and getting tested regularly it would be a problem for me.
I have known people agree things like no Grindr/internet stranger hook ups only private parties and swingers clubs for safety and traceablity
My experience is that far from taking anything away from your relationship when the person you love comes back high on hormones and feeling blissfully fulfilled they actually have a lot more to give to you emotionally because their cup has been filled to overflowing
I find it very fulfilling and I feel I learn a lot about the people I love as they grow and learn new things about themselves from the new people and experiences they have had
Like I say, not for everyone, but you don’t have to do the party line just because that’s the norm
You can invent whatever rules work for you and your family.
