SR I'm going to provide some unasked advice that helped me back in my 20s when dating a manipulative man. I was advised to no communication for 30 days. Nothing, no phone calls, texts or emails. This gave a time of clarity and strength at a time of feeling weak and heartbroken to be convinced to go back. It really helped me so much. If you choose too, let him know this is what's happening and he must respect your request. Then you can decide on your own where to go from there. I hope this suggestion is helpful.
I pray you and your son find peace and healing in this difficult time.
Hugs
