The hurt and the pain are unbelievable. I'm sorry your are going through this Resilient Soul
It seems like your WH has done his best to strip you of all security. Emotional and financial. That is a really hard place to be.
I keep trying to figure him out.
You won't be able to and will need to focus on you. It is so hard not to do the pickme dance. I liked Melanie Beattie books to learn how to turn my focus to "me". If you can even concentrate enough to read. At 4 mos, it is pretty hard to focus for very long.
He said he wanted to have more time to think about it...I felt like a side chick.
Trust your gut. You are worth so much more and you are fresh in the hurt of abandonment, so you can't see it.
How do I move on from the pain?
Baby steps. The waves are huge right now but they get smaller and less intense with time. You grow stronger too. Like working out emotional muscles, they get stronger. It takes time.
Focus on self care, journal, exercise, vent on SI, seek IC, family if they are helpful, feel what you feel and release those emotions rather than trying to suppress them. Survive.
I'm not worth it? He has rewritten history, telling everyone we had a terrible marriage where we would fight for over a year, which isn't true.
He said he wanted more time to think. It isn't that he doesn't want you, it is that he wants more/extra. There is nothing wrong with you. Look up Melanie Beattie. I liked daily devotional type books of hers and others just to have specific thoughts for the day.
But I can't do the work for him.
As hard as it is, you need to help you. To turn your focus away from your WH. Detach/180/set boundaries.
