1. SHE decided not to go out. You did not force her. SHE.ddecided on her own..
Regardless of what you did or didn't do, she choose not to ho out.
2. SHE is not happy with HER decision and blames you. Regardless of what you did or did not do , she choose and is blaming you.
Accept that she will be unhappy and blame you. I am not saying accept her blame nor abuse. But accept that in her current state of mind this is going to happen. Just like rain on a winters day. It is normal and not always pleasant, but it is unavoidable.If it rains it rains.
3. You do realise how childish her antics are. If she wants to be childish let her off.
4. That has to be one of the lamest excuses I have heard to NEED to separate. Don't buy into it. No matter what she spews ALL she is saying is that she is not happy.
Accept that she is not happy and know that you cannot fix this.
5. As long as you keep your focus on repairing things you will be hurt by her words/actions and those feelings of despair and hopelessness will fester inside of you.
It is good you try not to think about your situation. II know this is difficult when sharing a house and kids. Please elaborate on what YOU are DOING to achieve this.
Best wishes
