I think the therapist is just trying to get to the root cause of your husband’s negativity and perhaps she is being devil’s advocate and saying things like, “Do you feel that this is healthy for your kids?” His response to her is probably, “No.” and then she’ll say something like, “If you feel that this is unhealthy, then what do you think you should do?”
I doubt she’s giving him any concrete advice to do anything right now.
She is telling you that it could go either way b/c you husband is doing something that is very dangerous to a marriage. He is “repainting” his past with a negative brush. He is choosing to only remember the negative aspects of your relationship and marriage.
This usually always leads to divorce when one spouse begins to re-write their past in a negative light. They stop remembering the good times and focus on only the negative aspects of their memory.
Unfortuntately and I hate to tell this, but this is usually a precursor to separation and divorce. It seems to me like he is lining up all his ducks to leave you and then justify it in his mind.
Were you manipulative 10 years ago? SO WHAT??? That was 10 blimming years ago!!! Heck, I was manipulative too a decade ago!!! All human beings can be manipulative!!!
Take this as a warning for the worst case scenario. If he continues this negative behaviour and he continues to re-write your history in a negative light, expect a divorce. I’m so so sorry!!!
