I have read about the cycle, and lots of other things. I imagine that is one of the main reasons for my current distrust. I know a month is nothing in the scheme of things, but every day is up and down emotionally, so it feels like forever.
Ugh, I'm sorry you're going through this. I went through something similar. Like someone suggested, definitely go to individual therapy.
I'll tell you how I handled it...
My ex was emotionally abusive and we tried couples counselling for a year. It helped on a superficial level, but the root of the problems never changed. Things would be good most of the times, but when they were bad, they were bad.
Once I decided I wanted to leave him, I made my decision and didn't look back. Of course he said he was going to change and blah blah blah. Maybe he would've changed, but he had plenty of ample opportunity BEFORE I told him I was done to make that change. Every once in awhile I wonder if he ever would've really changed, but I don't regret my decision at all.
It's ok to be done if that's how you feel. It's also ok to keep with your agreement of counselling and see where it takes you, but definitely look in to individual counselling so that you have someone that can help you with this rollercoaster of emotions.
PM if you ever want to talk.
I am having similar issues to the OP. The bolded really spoke to me. Thank you.
Trust equals words plus actions matching over time. One month is not enough time to build the trust back so of course you are still questioning everything. I say minimize contact with him to business reasons only for now, and give it the full 6 months. During those 6 months really focus on you and try not to think about if he is doing what he needs to do or not. Focus only on what you can control.
