Lifsn - I usually try to be the very opposite of blunt in relationships, ime, there's always someone else willing to do that. For myself, I feel that the journey towards understanding is the answer. Bluntness can be a shortcut that the person is not yet equipped to hear.
But, here's an idea: Both you and your husband find emotion/love threatenting. That's why you are together. That dynamic started before the fact you had a relationship with someone else while engaged to your dh. Now you have had your dc, and things have changed, a bit, for you. You have experienced the fact that love/emotion need not be overwhelming, or quite as dangerous as you thought.
That makes your entire relationship with your dh very different. I suspect it no longer works for you. And has become damaging. So, now you are wondering ... .
And here you are, posting to find out if this is the norm, if there are others in your situation, how other people manage intimate relationships/intimacy.
I think you're at the start of a long and complex journey.
