Im not trying to install fear, but definitely take it serious. Some men do not take breakups well, especially when they don’t want the relationship to end. Even if you think he won’t do anything (and that may very much be the case) you need to protect yourself and your babies. Is there anyway you can take the baby over to his parents? Or have someone there with you when you return home?
I had almost an identical situation. You need to establish boundaries and he can’t be coming to the house anymore . You need that space so make him look after baby at his parents or have a day out. He will be feeling a loss of control in kids life so he’s trying to influence that but not sure how. Then get ready for his five stages of grief, you will be the number one enemy. U need to make sure u have as much custody as possible. Don’t give it away will make it hard if you ever need to go to court
It will calm down but you need him to not be in the house and just be ready when he starts experiencing that loss but it will be fine we all go through this
sounds similar to my story
Maybe a restraining order, custody agreement
