'there's no disputing he misses me, loves me, he just can't deal with any negativity and that's why I feel he won't contact me sadly'
I don't want to be indelicate, but if he loves and misses you so much, why would he have said the things he said?
He wouldn't have.
He hasn't got round to doing anything at the moment, but that doesn't take back what he said- he still feels it inside, at least some of the time.
At the very least, he took his feelings out on you.
And if he can't handle any negativity- tough shit, he fucked up, and should be putting it right.
What about your needs and feelings? They matter too, and he isn't acting like they do.
So you are in your head in a relationship with a guy who's:-
a) said he doesn't want to be with you,
and
b) isn't bothering to try and make it up to you and make you feel better.
How can you carry on with him, knowing that any moment he might be thinking that he doesn't want to be with you? He might say the same again at any time in the future.
