Most Helpful Guy
It takes two people to have a relationship. It sounds like he doesn't want to be. Sometimes if you let things settle more you'll both find that you do love each other. It's an overused trope, but the "if you love something, let it go" story does work sometimes.
If it's meant to be, it'll be. You can't force it. You can't make him love you.

Well, you already did your part by confessing your feelings for him.
It seems as if he also cares for you, but is hesitant on whether he should move forward or not.
I would request meeting up with him.
Don't force the issue any more.
Now it's clear he knows how you feel.
Take things from there.
Try to enjoy his company if he does accept your offer to meet.
Start shifting the conversation into regular ones,
"Hows your day?"
"What are you plans?"
"What did you get for Xmas?"
etc. as a way to wheel him back in.
Don't constantly keep asking to get back together with him, you will look desperate.
Just play it cool.
And take things day by day.
He seems as if he was hurt by your relationship.
Whether he chooses to move forward or keep things as if, solely lies on him.
But as a woman, you know you did your part.
