Need to vent. I’m sat here on holiday at centre parcs with my little one which I booked for his second birthday. I asked my ex partner father if he would be able to take us there as I don’t drive. He usually helps take us places if we have appointments and has dropped me and DS on holiday but with my LO father too. I booked it for me and LO only this time as his father is working and can’t afford the holiday either. Little did I know someone would invite themselves along. My exes father said he was travelling that way to go see relatives anyway so asked how many rooms I had booked. As there was an extra room he decided he was entitled to it. Without paying anything towards the holiday. My ex found it weird me and his father had booked a holiday away together and they are now arguing. I didn’t book it, he came along. Then decided to tell people I asked him to come. Then he’s asking why I didn’t book him activities that me and LO are doing. I said I didn’t know you were coming. He said why would I just take you there and leave. It’s less than an hour and a half away from his house. So then he starts invading everywhere we go and whatever we are doing. Even using our private bathroom and peeing all over the toilet seat. Then complains he doesn’t like it as there is 2 many trees and walking. Which he knew when he dropped us off before. Now he’s asking me to tell him when we will go swimming so he can come with us. I don’t feel comfortable especially at some of the remarks he’s said to me in the past. He says he is not visiting family in the area now and he only said that he might visit them. But decided to just come with us. He is trying to rush us doing things saying he’s cold wants to go back to the lodge doesn’t know his way back so we have to end what we are doing to take him. He’s just telling us to hurry up. But today, to top it all off I asked him to put LO in the buggy. And he decided he would pick my 2 year old son by his coat near his neck and nothing else. So my little one is dangling and screaming. I told him to never touch him like that again and had a go at him. He tried defending himself saying I asked him to pick him up. I said yes. Not his clothes. Now he’s went straight into his room in a huff. And I’m laid here fuming. I nearly slapped him right there n then touching my LO like that. And no apology either. He’s also been making hints at coming on our next holiday I told him I booked. I’m just mad as fuck. What gives someone the fucking right.
