Would you rather go though this now, or 10 years from now with several kids? Count your blessings. I was married at 29...three kids, 12 years later W tells me she is unhappy bla bla bla. She drug all 4 of us through the ugly mud of divorce. It is now 10 years post divorce. Best worst thing to happen to me.
There are so many layers to this. Ultimately it comes down to your personal growth. You have to really question everything you believe. During this period, study like a madman. Learn as much as you can. Make any changes you believe are important. This is about fixing yourself. We all have so many issues. Your W is a mirror reflecting issues back to you. Everyone else you interact with is as well.
Your #1 priority with your wife right now is to listen and validate her FEELINGS(Angry,sad,happy,scared, etc). Your #2 priority is to practice this skill with everyone you interact with. You make the conversation 100% about them. Do not share your story.
Listen/Validate repeat.
When you are not interacting with others, focus on tasks that are directly related to you goals. You goals should be things under your control. Not things like "saving the marriage" but rather, "Validate my W's feelings" or paint the living room, or wash the car, or learn some new work skills, or plant a garden, or make 5 people laugh today.
