I'm a bit confused. The T did not tell you that your kids are in pain "because" you are not dating.
Here's what you said:
So i responded to the therapist "are you saying that since I am not dating, it is impacting my children negatively?" She responded that dating may help them and me (understand she is not my therapist and often the interaction she has seen with me and my son is teasing each other). While I take responsibility for not being the husband I could have been, I resent that I am being told that it is my fault that the kids are hurting because I am not dating.
I think you are putting a spin on her words that isn't there. To be fair, chances are high that she is saying things based only on what your kids tell her.
So, she is sensing or hearing directly that to THEM, you don't seem happy "enough", and in some way they feel responsible for it AND OR impacted.
That does not release your ex-wife from anything; it just means that as of now, not the past 8 years but today,
they are affected by their perception of your happiness, or lack thereof.
Maybe it's a matter of you "acting" better, and or just telling them how you feel.
But the resentment of the T, seems out of line, at least based on this one interaction.
But hey, that's Just my .02
