It sounds like you have some decisions to make. You deserve to be happy. It takes two people to make a marriage and relationship
work. It sounds like you two are roomates and lack emotional/sexual intimacy and you want more. I don't blame you; i would too.
There could be many reasons your wife is unable to be intimate. My first marriage ended and i was unable to be due to childhood SA.
I just wasnt ready to deal with any of it yet. But i dont know what's going on with you two, how deep your love/bond is, what wounds are there etc. All i can say is please be kind/gentle with your wife as you dont know what type of battle she might be fighting, and i wish both of you well that you can find healing and get your needs met. Maybe you'll meet those needs together or apart. It's up to you two
