Modelc, I'm sorry that you're feeling unsupported.
we are ending the marriage.
If, after four months of marriage, you've decided to divorce, the options now would involve getting a lawyer. Your lawyer will also discuss the split of your marital assets, including your home- (unless you can have your marriage annulled.)
Since neither of you have filed yet, you will need to file first. Since he is moving out of your home for good in the next four days, you must stop emotionally texting him about why he left for work without saying goodbye to you.
When a marriage is over, it is best to keep contact to a minimum. That will give you the stability that you desire and allow you to detach from each other. Keeping it civil means minimizing the emotional content of the communication with him. Unfortunately, this means letting each other's lawyers do the communication instead. Good luck.
