Most Helpful Girl
Having a serious talk by text is not a good idea. It would be better if you could talk to him on the phone at least. It may also be a good idea to take the break and not talk to him. When you get back from break you could explain that you were interested.
It's too late now but I think it's a bad idea to tell a guy you're not looking for a relationship unless it's true. Instead you should've said you wanted to take things slow. Don't ask him to be monogamous at this point since it's rocky. You should go out on other dates too. Don't put all your eggs in one basket so to speak. I don't mean to go sleeping around either.
