Although it seems like everything is out of your control at the moment, you have already taken control, you’ve done the hardest part and moved out. That’s an amazing step. You have taken control of your life and your child’s. It’s better you have done this now because 6 months down the line, you’ll have a baby and a partner who cannot or will not be there to support you because alcohol comes first. Unfortunately I’m speaking from experience.
He won’t be able to wake up to support you with nightfeeds or changes, he can’t help with driving, family money will go on alcohol first. The effect on your mental health and self worth will be life changing.
His behaviour now is awful because he is being forced to address it, (due to the conviction) and he doesn’t want to address it. There’s the old saying that you have to reach rock bottom to get help, but in my experience sometimes that isn’t enough. Some people just can’t give it up.
You have your whole life ahead, a new, exciting life, as does your child. It sounds like you have family support too and believe me, the hardest part is done. You left. Many can’t do this.
This is HIS PROBLEM TO SOLVE. You absolutely cannot fix this.
Good luck! You are stronger than you realise!
