I think it’s wise to give him a chance. I gave my first husband no chance. I don’t regret at all and I am pretty sure we’d still get divorced at some point. And we both found much better match for 2nd marriage but he held it against me for awhile that I had zero interest in working on it. It’s wiser to try something so at least you’ll feel you were fair and didn’t just give up. Find a therapist and see how it goes.
