Stupid men but maybe I'm dumber

I married my now ex-husband after knowing him a very short period of time. He was in the military. We had a pretty good relationship but one day he just left and divorced me soon after retiring ... and has said not much for three years. Now after therapy he says it was a mistake and he wasn't himself because of things that happened while deployed. I always loved him, and I knew that's what happened, but I lost so much when he left and it was very traumatic and hurtful. Like it felt like someone I loved died and it scarred me. I'm not really with anyone, and I care for him but I feel stupid for feeling this way, and I don't really trust him or want to even though I know he isn't lying about this. So what do you guys think? Most everyone says and common sense says run away. :/
