Too little too late for husband to be invested


I understand the manual I’ve had for my husband but over the last few years I’ve given up on even caring if he is the person I wanted him to be. I feel like I’ve checked out of the marriage and I’m considering leaving. Now when he tries to help around the house or engage with me I think ‘too little too late, don’t bother’. I would like to try and not feel so low. I would consider trying to reconnect, even if it’s just to get to a great place of being friends if we split.
