OP - I don't know how old you are - but it sounds like both of you are young and not ready for anything serious and long term.
You said yourself that you are not after moving in together - which is a natural next step for a relationship that it long-term focused, etc.
So - 11 month ago - he met you, and thought you were nice (=decent), and attractive (=shaggable). And, he wasn't at a place where he wanted to be in a serious, long-term relationship (=he could see a fling with you for a few months)
Is that really different from a start of many relationships? People meet, they don't know how it will turn out. They know they are attracted to each other.
And unless they have some sort of biological clock pressures (like many, like I did have at some point) - the focus is not always on the long term, not from the start...
However, as with many - people spend time together, and, sometimes magic happens.
They fall in love, they stay together longer than they thought they would. Or, they don't....
So - what exactly bothers you in what he said about 11 month ago?
You clearly are having a relationship - despite his initial intentions. You are on holidays together, etc.
They only thing I can think of - is that you are scared to admit to yourself that you actually want more, including moving in together, eventually.
In that case - I am sorry - and it's a tough place to be.
In that case - at least it's still early days and you can leave and try to move on.
