Honestly- i'm judging you and I have 5 children, with my husband.
I am the eldest of more children than you have, and I am no contact with my parents. My childhood was robbed from me, and I had more stability than what your children have and it still wasn't good enough.
Your children are the ones who suffer from your poor life choices. Its not good enough. There's not much you can do about it now, but you will see the fall out in years to come and hopefully you will take responsibility for your actions- unlike my parents.
