Hi OP
Just to echo what others have said, these people sound awful.
I really feeli like the more time you have away from your H you will realise and remember more and more of this things they say and the way they have beentrying to wear you down. MIL sounds evil, but I think that's possibly true for a lot who think that no one will ever be good enough for their precious sons. fIL sounds like an idiot too. If you had just one of them on your side, I could see some ope for you and your DD. as it is, none of them are, and although I'm sure you will try and find good in them all, it seems that they don't have a decent bone in their bodies between them.
Your dP should be on your side. No matter what. Your married him and probably uttered the words to love, honour and obey each other, not him his bloody family.
He has and is letting you and your Dd down more than is acceptable.
He has walked out on a 5 month old and thinks it's okay to 'pop in' like a neighbour might to see his own Dd. he has been out for a night out whilst you've been left dealing with the accusations and feelings of guilt. He hasn't had the decency to apologise to you or your DD. he is acting beyond reproach in my very honest opinion.
I really do think you need to move out for a while. In a way, him leaving you at home 'stewing' and dealing with all the demands of such a young baby is also giving him power. I'm sure you don't want to have to leave, but I think that would be the most powerful message you could send. Don't tel him, or ask him. Just go. Your mum sounds lovely and she will help you. If you get some distance and see how someone who properly loves you helps you, you will see that your H has an agenda. His own and his family's. it doesn't matt whether he is trying to protect his future business, or whethe his Evil Parents are controlling him, he should be protest guy from all this crap.
Really, please give yourself the space and time to see everything that has gone on. I know with a young baby you're probably too busy to properly think about what's gone on before and is going on now.
Maybe a separation would be a good start, and make your H realise that enough is enough.
I was married for a long while and was unhappy for the whole time. I stayed because I thought I had to because I'd taken those vows. I also had massive issues with PiL. I was divorced about 13 years ago and even now, their words and ideas and ways affect me. The impact they had on me still has a hold and a has affected me in terms of my confidence. You sound much stronger than I was, but they will grind you down eventually and may even eventually poison your DD against you.
Every post you wrote just makes me think, enough. You've never had a good relationship really, as it's been all take from them and all giving from you.
I hope what I have said isn't upsetting or rude to you. I don't mean it to be. I've been following is thread from the beginning and am so so angry on your and your Dd's behalf that I just had to post. None of this is about the job it's about controlling you. I'm so sorry you're having o go through this and that you married such an arse and into such an evil family.
Look aft yourself and your DD. she is still very young and she needs you more than anyone else.xxx
