After a year of doing it on my own, and learning to expect next to nothing from the ex, I have accepted a lot and moved on. However... the ex continually blows off my son, and this weekend was a prime example -- long story, but suffice it to say that he disgusted me with his selfishness. I shouldn't be surprised anymore, but when he treats my son like crap I get ANGRY, and I can't let it go. I know I should (emotions=control, right? Indifference is the goal, right?), but it's the mama bear coming out.
Do I need to go back to therapy? Is this normal and/or acceptable, or should I let it go?
