Going on holiday with my ex?

My Long distance ex boyfriend broke up with me 3 days ago. He said his parents said it's not worth fixing bc of my physical health and my dad dying. He said he's been feeling distant from me ( could be literally because hes been busy as soon as he moved back in with with his parents lol) and that he thought it'd be too hard to see eachother 3/4 times a year ( even though it wouldve been for long periods of time and will be more frequent than that) but we're meeting up in 3 weeks still because we made so many reservations and non refundable bookings it's too much to lose out on and we're seeing if we can be mates.

We have talked breifly everyday since then, about lighthearted things and made jokes. If I initiate contact he replies instantly but he doesn't initate it. I tried to not contact him today but I saw he's seen my snapchat story and I'm his only friend on there bc it's not used commonly in his country so he's gone out of his way to check on me lol. I had to contact him later on as I got a call about a restaurant reservation needing to be cancelled due to someone booking the whole place for a wedding last minute. I didn't remember the booking so I asked him if he booked it. etc etc our conversation felt a little too...friendly. Like after I told him I realised it was the place we were going to watch the sunset with a view of London together but I wanted to go to another place anyway so it's chill he said " it might be so be wonderful if we go to that place" and told me he was so excited for the trip... I feel like I'm getting mixed singles here... please help😂 I'm going to limit contact for a while but we needed to arrange things for the trip and are going to video call on Sunday to arrange it :)
