Now he doesn’t want to try
I quoted the title because it's all it matters here.
First of all 'welcome' and sorry you are here. I feel you are overwhelmed and is going to be one of the hardest trials of your life.
You will find sympathy, insight and guidance here that you won't find anywhere else.
Now about the title:
The most important thing when dealing with a cheater, if the BS is considering to take them back is the following
The WS must be ready to do anything to regain the trust of their BS. And by Anything I mean Anything. If you ever see that "anything" has a line, don't take them back. They are not ready.
Read about the 180, is what you should do right now.
What he is doing is seeing that you still care, and manipulate you in order to get forgiveness without changing his ways.
Hard 180, let him understand that he is gone, if he ever wants in again he'll have to earn it, prove it, and you still have to decide if you will ever say even a "maybe".
You need to protect your emotions right now, because it will get worse with time, you must do damage control, not letting him room to hurt you more than he did already
Don't talk to him in terms of "we". There is no "we"now, there is just You and an asshole.
And all should be focused on You now. Not on him.
You should focus on healing yourself.
This is not harsh, this is to save you a world of pain.
