(Sorry for dramatic title) so as not to drip feed. I divorced exh 10 yrs ago. We shared custody but over GCSE and A Levels son (now 19) stayed full time with me so I could help him study and keep him focused. I paid for all his ex curricular activities and he always had latest kit as I was a higher wage earner and his dad couldn't afford it. His father has mental health issues and is very emotionally manipulative. Makes kids feel guilty if they choose to have night out with their friends on a night they are staying at his. Anyway. Now ds is 19 he is doing really well at a Uni course he loves and has a part time job and lovely girlfriend. I'm so very proud of him. But he is spending 6 out of 7 nights at his dad's. Because there he gets to drink openly (I can't have that here as I have 3 other children ages 6 - 11) he gets to be a lad over there having his girl friend stay. I don't allow that here. (My own choice again considering small bros and sisters.) When he does come to stay he eats with family and spends rest of the time in his room. He fills up on home cooked food and clears off again. I don't know when he's staying and when he's not. He works nearer me than his dad and so sometimes will only stay here for convenience. I feel a bit like he's taking us for granted. I'm marrying my new.partner soon and DS wants nothing to do with wedding . I feel so let down. I know all I have done for him is just my motherly job but AIBU to feel let down by his recent behaviour?
