Hi first time posting on here I'm currently separated from my husband after 20 years relationship 14 years of marriage, my marriage was abusive physically emotionally financially and mentally aswell as cheating its been over a year now since we split, my oldest child nearly 19yrM has suddenly decided the sun shines out his dad's behind after years of being bullied by his dad and virtually ignored now he barely wants to see me or speak to me he hates that I've moved on and he feels sorry for his dad yet when he wants money or lifts somewhere he rings me im constantly in tears because me and my son have always been close, he knew about my new partner and was absolutely fine with it he'd go out for drinks with him ask my new BF to lend him money and got on well until his dad found out I was with someone. Now my son rarely comes to see me but I'm always there for him if he does come up he has a stinking attitude with me which infuriates my BF my 2 younger children get on with with my BF but my oldest now has done a complete 180 on me and dad's the best thing ever, our son was beaten up by bullies and his dad wouldn't even get up off the sofa he's lazy they live like pigs he never does anything with any of our kids blows his money on crap so they always come to me if they need anything ( I'm their mum so I'm not complaining) my oldest son and his dad never got along until recently because his dad can no longer control and manipulate me he's doing to him instead and now it's like I don't even exist unless I'm dishing out money I don't know what to do anymore I'm constantly crying it's absolutely killing me I've always put my kids first I chose to move on because my husband had plenty of chances to change his behaviour and didn't and therefore I was in a very unhappy marriage now I'm happy and suddenly I'm the bad person , what do I do I can't lose my relationship with my son my life wouldn't be worth living if that happened please advise
