“They’ve got an addict with mental health problems as their mother”
what a nasty way of putting things.
Their mum has mental health problems and addiction issues’ would be less nasty.
She hasn’t said she is an alcoholic in active addiction, she said SUFFERED issues with alcohol not ‘am currently suffering’ and people struggling with mental health issues do often develop a poor relationship with alcohol as a shit coping mechanism but don’t always become alcoholics. Alcoholics don’t always spend their entire life span in active addiction either. There is recovery possible but unless it’s rock solid recovery, life challenges can test it and make them vulnerable.
But no OP, I don't think a baby in a home where there is already three children’s needs to meet where their mum might be more fragile to struggling and relapsing with either mental health or using alcohol is a good idea, but I also know an abortion you really don’t want can cause a huge mental health relapse which can include an increase/relapse of alcohol abuse. So baby or no baby the outcome can be the same. A broken mother and unsupported children.
As your partner is the one trying to hold the glue of this family together his needs and thoughts do matter, but ultimately he needs to realise it’s not always a case of terminate and everyone moves on, he could be dealing with a massive fall out from a coerced/forced abortion which will see him picking up all the pieces anyway.
You dont know which way the cards will fall until you make the choice either way.
If you choose to terminate OP please make sure you have a pre planned ‘crisis’ plan in place so your partner knows who to contact and how to help if your MH dramatically declines and/or any addiction issues become critical.
