7 years bad luck or..!

Boyfriend of 7 years left me because he felt that we were arguing too much. During the argument I must’ve said something that really touched him. I am going through depression and he asked me why is my relationship status on Facebook single and I literally bursted all my feeling out which majority I didn’t mean. Communication wasn’t working well before the argument and I decided to let everything out at that moment without the intention of offending him and normally we manage to sort it out no matter what but this time he decided to move on , Within 2 weeks he basically moved and keeps telling that he has found someone else and he will never and never come back to me because he doesn’t wanna hurt the other person’s feelings. I apologised and he said he accept my apology but he just wants me as friend. However we are currently out on a vacation which we booked about 4 months ago , because I invested so much money I decided to go and have a break from where I live and also try to settle with him, but no chance at all I decided to respect his decision however there are certain things that I don’t understand..he still opens the door for me before he get in, asks which food I wanna eat, walk around naked in front of me, drinks on the same cup as me, uses my shower gel etc.

Why would he do that? He deleted me from all social media and said he doesn’t wanna have anymore business with me.

If that so why did he come to the holiday? His answer: “because you forced me and you said we were coming as cool people.”

Obviously not I came to sort things out. I’m in serious pain all I do is cry even in front of him but he does not care at all.

Any advice suggestions?
