My mom had the same problem with my father. He never admitted I had problems and may have been what you & others would call neglectful
, towards my younger brother (an NT) and I when we were little. (He never watched us closely, took us to stores like Home Depot & Lowes, left us wander around his & his "mistress's farm" alone, him & his family made sick comments & taunted me constantly, etc. My brother especially & I came home sick &/or injured a lot as well.)
It does not sound like your husband is doing anything to taunt you by harming your child like my dad did to an extent (it was technically what you would call abuse though, he just pushed the limit as far as possible w/o crossing legal lines, just plain wrong)
. We no longer have any contact w/ him! Yeah, I changed my name too
!
I would trust your gut, you seem to be in tune w/ your son from what you are describing. Separation from your husband sounds like it will really benefit your son. (If you divorce, make sure to do whatever you can legally to keep him (your son) safe on visits & give him an emergency plan in case of a problem while visiting.) Also, ask his doctor/psychiatrist, etc. about putting him back on his meds or changing them & consider therapies through a private agency, hospital, or his school to help w/ issues (Speech, Occupational &/or Sensory Integration, etc. depending on your son's needs).
Emergency Plan tips: (p.s. If you are offended by this or do not think its necessary, my apologies & please ignore. I made this list based on own experiences.)
Warning (they may need to be adjusted depending on scenario):
1. Send in matching clothes w/ a sibling (shirts, sweatshirts, shoes, etc.) so they match (won't work if an only child sorry)
2. Have him plan to approach workers (cashiers, etc.) if in public & he gets upset for some reason to call you; he should probably carry your phone # & address w/ him in some form & memorize it in case his dad is like mine (he might take it or taunt him/aggravate his symptoms all day for fun)
. (Sorry, my dad did this when I was 6-8 & 10 on last visit/not fun so I'm paranoid in this area). He should know what to tell the worker he approaches so he can contact you (you decide what that is).
3. Have him be prepared to go to a neighbors if their is a problem. That is if this is an option (I wish I had had it!)
4. Above all, make sure you son knows he can trust you for any problems he may have and try to keep him as relaxed as possible
.
Sorry message is so long,
Good luck
