i am glad that your out of your situation and i hope that you are doing well.
my mother stayed with my abusive father for almost 22 years before she left.
but everyone situation is different.
for example enduring that type of lifestyle. it effected me and my siblings our whole lives, even in relationships and parenting. my brother is abusive to his daughter and she is a teen sleeping with a lot of guys to mask her pain.this is what i did when i was in that situation.
my insurance paid for my therapy and medication. and the therapy helped me a lot.
