I don't speak to either of them anymore but OH takes Liam round there for a few hours on a Sat or Sun. Anyways, he always comes back telling me how they have pissed him off in some way or another. Last week Liam came home and stunk of smoke! His Dad refuses to leave his living room to have a fag and apparently just lights up one after another. I got really angry that oh didn't take him out the room and said if this happens again he won't be going round there. Yesterday they went over again and his Dad carried on smoking so OH asked him to stop to which he replied 'it's my house I can do what I want' so OH spent most the time with Liam in the kitchen (what's the point them even going round if they don't even spend time with them because of the constant smoking?!?) Then I was told that OH's mum kept saying to Liam 'Mummy loves you'... WTF!?! She doesn't speak to me so wouldn't be saying it in reference to me and I was told it was clear she was saying it as if she was his mum. OH said to her 'what are you doing, you're not his mum' and she just tried to brush it off. This is the same women who said I was trying to turn Liam against them by saying they were evil to him (I've never said anything like this!). Tbh this has upset me more than the smoking because HE IS NOT HER SON and it worries me about her mental stability if she is saying things like that! What would you do about this? I don't really want him going round there anymore with this sort of attitude and they won't be looking after him when I go into labour anymore.
