Since me and my ex don't speak my mum does the contact with him. He takes her every other Saturday night. On Saturday he picked her up and he was dressed and he never is he's always in work clothes as he works to 6 and picks her up at 7. We smelt a rat when he came down dressed but we let it go. So my mum messaged him around 9 to see how the child was getting on and there was no response all night until 10 the next morning. So then he left her back Sunday and my mum said to him where u out last night or something and he said no no I just wasn't on the phone so we took his word for it but knew something wasn't right when he didn't send any photos of the child on Saturday which he usually does. Mum said to him any photos from Saturday and he said no and put his head down instantly we knew something wasn't right. So during the week I found out it was his friends 21st birthday and he went out drinking and left the child with his parents. When mum confronted him about it on Wednesday he said what does it matter to you and she said it's the fact you lied and couldn't tell the truth to make other arrangements when it's your time with your daughter to sleep over. So me and my mum decided she won't be going back up if he can't be there for her because it's not the first time he's went out and left her with his parents because his mates told us. Do you think we're being too harsh not letting her go up to stay? He's still yet to apologise it's the fact he lied about it and couldn't just be honest and make other arrangements idk are we being too hard???
