"Another reason I think he has zoned out of our “relationship”.
When I say to him he’s my partner, boyfriend, he looks at me weirdly and says “we are just friends”
this is so confusing as he always sends me “love you” nighttime messages. It’s extremely confusing and it’s messing with my head."
You sound like you keep trying to live in and push this false narrative on him and perhaps his family that you two are in a relationship fully knowing that you two have never been. You are confusing your own self.
I'm not sure if you truly do not understand everything pertaining to this situation, or committed to living in this disillusionment.
No one has to be in a romantic relationship to express feelings of fondness and love. No one has to be in a relationship to enjoy each other's company.
His family may know you as a girl who's a friend. Perhaps he was confused when he allegedly asked you to be his girlfriend, perhaps he meant a girl who's a friend, perhaps you were confused, failed to ask questions so he thought you mutually agreed to be friends, perhaps it is you who twisted the context of his words to mean something else, etc...
You have used quotations around such words as relationship, and couple.... perhaps this is admission that you are fully aware of a friendship dynamic all along.
If you are fully aware and are in denial or trying to victimize yourself....it may appear to him and others that you intentionally are targeting him and his family hoping to gain something.
Perhaps he feels like you're unstable and have been put off by how you view yourself as in a relationship with him...and has been putting space between you and him which may be why he won't visit or set up one for you to... perhaps it really is the lack of finances..and maybe things happening in his life.
Perhaps he enjoys you as a friend and trying to create boundaries now.
If you are a more functionally capable person than he may be, why have you chosen a person whom you may never be compatible with for a potential future together??
Anyways, regardless...I think it would be best for you to leave him alone.
Your alleged feelings aren't reciprocated.
It will be weird and awkward between you two now.
Perhaps therapy would be beneficial for you before returning to the dating scene.
Find someone you're compatible with, and who reciprocates your feelings.
