advice from abreva,coparenting

Ok,someone suggested I ask abreva. I am tightenning up NC with ex hn,after a big slip up. Keep in mind I had to put everything through the court a few years ago,because he was dishonest and I didnt trust his parental decision making,etc. He text me today asking if he can take d5 to his state for a week and travel around with her in his little plane for their visit. I said I would like him to email me details about it because I realuze he is in transition(moving out of gf), and I would actually prefer if he either saw d up here or was settled in a house,so she wasnt being trapsed around state,and there was some stability. His visits have been few and sporadic over the past few years and d tells me she isnt comfortable. I want them to spendvtime but I want it donr right. Actually that little fathet daughter trip sounds nice but only if she knew him better. Anyway he ask me in text why cant I talk about this and I said again,please email me I dont want to fight,or be bullied.when he asked why I am doing this I said because u are a habitual liar. Anyway any pointers on NC and coparenting???sorry if a lot of typos,doing on my phone. PS I want to make sure I am doing the right thing for d and not letting my anger come into decision making. There is something dubioys about his plan,I dont get why he suddenly wants to travel around,if he is in trandition.something not sitting right with me
