There is a combination of him being too busy & preoccupied with this woman (to feed his ego which is what he needs to get by) and him putting his head in the sand and ignoring your whole situation. He does this as a coping mechanism, i don’t think that he and most abusers can deal with problems, they put their head in the sand and ignore it rather than face it head on. If you think about it, abusive men are horrible during the relationship. It makes sense for them to continue to be horrible when its over, it doesn’t make sense for them to be nice as its not them. My ex was horrible to me when we were together, I hoped to be friends and civil after we split up, to have no bad feelings. He continued to be horrible, I think I didn’t appreciate it that this was just him & he wasn’t capable of being normal or decent. X
