I'm sorry in advance that this will be long. There's a lot of history and the back story is necessary. I am worried about the influence of my dad on my daughter (12 weeks old) but it would completely devestate my mum to restrict her contact with her granddaughter. There are several aspects I need help and advice on.
My dad is a very difficult man. He is I think extremely emotionally abusive. He has been diagnosed with depression but I am unsure whether there is some other mental health disorder which is undiagnosed (he lies to the GP). His default reaction to any adversity in life is rage. This used to be directed at me and my brother but since we left home this is focused solely on my mum. He can go months being very nice and kind, he's very good at DIY and loves to help people. But then when something goes wrong (can be quite a small thing) or there's any kind of slight disagreement in the family he will just turn. He becomes so angry, shouts and yells, says terrible things, is menacing and hostile. This can go on for weeks or months with long periods where he just completely ignored your existence (as a teenager living at home with him he once did not acknowledge me or speak to me for three whole months). He also gaslights when he is in these episodes (and I know the term is bandied around but I mean properly). He hides things like keys etc, breaks things and denies it, rewrites history, swears black is white and makes you question your sanity. He has had therapy, he's on antidepressants, he's done CBT and mindfulness courses. There have been numerous 'showdowns' and ultimatums about his behaviour. Things will improve for a while and each time we all start thinking maybe he has changed but eventually he slides back to his old patterns of behaviour.
My mum is a kind, patient, gentle woman. She has spent the last 35 years trying to 'fix' him. She spends a lot of her life miserable because of his episodes. We have a very close relationship and speak or see each other every day (usually just us, not with my dad too). I have thought for as long as I can remember that she should leave which she knows but does not have the strength to do / chooses not to. I feel like my heart is actually breaking watching how much he hurts her.
Through the years there have been times when I gave cut him off completely but gradually for my mum's sake I have let him back in to my life. For full disclosure out of me, my mum and brother I am the least affected by him and his behaviour. I have never been afraid of him like they are. I call him out on his shit and will say it like it is (have told him to his face I think he's an emotional abuser). He hates this as he can't stand being disagreed with. Also, for full honesty he was physically violent with me a few times growing up (kicked me quite hard a few times etc) but as I said our personalities do clash and I always gave as good as I got (verbally as I was obviously no match for him physically). I have told him that any relationship we have is for mum's benefit only.
When they found out I was pregnant both my parents were overjoyed (it's their first grandchild). They immediately offered to provide childcare for her when I go back to work and were generally very excited for the future. My dad loves kids and we all thought maybe this would be a fresh start for him. Looking after her would give his days meaning and purpose and he seemed very positive about the future so all was well. We were all very hopeful.
Fast forward to this week. His estranged step father died (virtually NC for 20 years) and he's gone into a tailspin. Screaming and raging at my mum to the point she had to come to stay with me. All our hopes that he'd changed have been dashed again.
I'm now wondering if leaving my daughter with him is an irresponsible move. I don't honestly think he'd ever hurt her but I want her to be influenced by seeing positive relationships as she grows up, not abusive ones. However, when I broached this with my mum she was devestated. She's so looking forward to having her when I'm back to work the thought of missing out on that destroyed her. I know people will say she shouldn't depend on her grandchild for happiness but what else has she got while living with him?
So to my AIBUs:
1: AIBU to accept their offer and let them care for my daughter (possibly but setting good toke midels for relationships). I feel incapable of hurting my mum by taking this away from her when I think it's basically her only source of real happiness.
2: OR AIBU to be so hard on my dad when he does after all have mental health issues? I am so unclear in my own mind how much of his behaviour is illness or if it's abuse? Where do you draw the line? And how much should you tolerate while making excuses because of his mental health? I'm so confused as to whether I'm a cold bitch with no sympathy for mental illness or whether my mum is just buying into the old chestnut that all abusive men are actually tortured souls who need a woman to save them.
Sorry it's so long and thank you if you've read to the end. Any opinions or advice are welcome. Thank you x
