Hi Pinky,
Reading your story, it sounds fairly similar to ours. I am a straight spouse married to a gay husband. I have been off this forum since May 2022 as it can be a very painful place, even while it is immensely helpful. Real struggles are described here, and there is very little sugar-coating. I hope that you do return to this post and continue your journey with the people here who understand what you're going through. There is no one who understands like a member of the community. And as time continues, you will find that you just want to be understood. By anyone.
My husband and I have been married over 21 years, together for 22 years. He came out to me in January of this year, and it has been a terrible rollercoaster ever since. He has not been unfaithful. We are still together, and as flawed as our attempt is, we are trying to make this work.
I want to assure you that there are other MOM couples who, like you, have remained monogamous. My husband and I hardly know what success looks like yet, but we are 10 months into our journey. There is so much time, growth, understanding, disclosure, acceptance, and peace to come.
It hurts like hell in the meantime. I'm so sorry that you are living this.
