I can’t help you with the two parent home thing, but I can say my son was also explosive at that age. He’s 13 and he still is, though now it’s more verbally than physically, which is an improvement. He also understands his own explosiveness and does work to control it about 80% of the time. However, he still FAILS at his attempts at control more often than not.
It’s something we’ve worked with a therapist about. It’s helped both rounds that we’ve done with therapists, but we are currently not in therapy because our last therapist cut his weekend hours, and we haven’t found anyone we like who works on weekends. (We live in a rural town, but I work in the City, so even making evening appointments is impossible for us.)
