Hi Confusedaboutit,
I’m sorry to read how you’re feeling. It sounds like your boyfriend is trying to exert some power and control over you even from a distance. Sadly it’s quite common for abusers to sabotage things like trips, special events etc to ‘punish’ you for having some independence. Of course you have done nothing wrong, you are entitled to be away and in a healthy relationship it would not be a problem. Perhaps you could use this time to focus on looking after yourself, and maybe take some time to write down your feelings about the relationship, his behaviour, what you hope for… it might help you to work through your thoughts.
Kind regards and keep posting,
Lisa
