I don't get what's so bad on himself trying to stand up in the way he sees correctly, he has slef confidence problems that no one except himself can change, no comment from other people can completely make you feel better unless you yourself feel better about yourself and he has lived all his life depending on others, now he wants to do it himself to feel ready to be by her side. Also tf does it matter if he divorced it's all damn symbolical, he didn't leave her nor is he distancing himself from her, he even said that he can go to her house and it's perfectly fine with her coming to his house.
What he wants is feel alright with himself to not ruin things with the person he loves and wants to support, how is he gonna support her when he can't even support himself.
