What will happen to us?

I've been preoccupied all week, wondering when Jay is graduating and what will happen afterwards. When I think about it, 2 feelings rise from within me:

1. Sadness
2. Anger

Why sadness? Because I feel certain about us breaking up. He will either leave me or we will be in a long-distance relationship.  He may be in a different country, a different state, a different city for sure. I'd have to re-experience long-distance again, similar to my first-ever relationship.

Feelings of anger also come up because I feel angry we haven't talked about what happens to us when he graduates. I spent so much time and energy cultivating the language to talk to the men I was dating last year. I would tell them on date 2, in month 2 at the very least, that I was leaving and to check-in on how they felt that would impact our relationship.  Jay has not done that. He has not asked for any of my input about my future. Leaving me to wonder if he even cares about our future. Am I in his?

Anger and sadness fuse together into one blazing ball of... pain. Hot tears burst out of me and I find myself unable to stop sobbing.

Why am I always the one initiating the conversation on "What happens next for us?"
Why hasn't anyone else ever cared, much less cared enough to ask me?

When B. was about to graduate and was planning his future a few months beforehand, I had asked him what will happen to us. He told me he could not guarantee the future nor give me a final answer about us. He "hate[s] long-distance." That's what he said, and we had already been in a 2-year relationship.  It was too painful accept then, but he was telling me:

"Goodbye dumb girl! I've been using you for the last 2 years while I'm here, and once I get to leave here, then it's good riddance to you too!"

If someone I was with for 2 years could leave me like that, then why wouldn't Jay (who I've only dated for 4 months) also say sayonara, baby! What else am I supposed to expect?
And if he anticipates long-distance dating, then why hasn't be bothered to have a conversation with me about it?
Am I supposed to just agree to it?  Because that's not how it's worked out for me when I've been the one to leave.

In my scenarios, all of the guys have gotten up and said "thanks, but not thanks" and then walked out of my life. How can he expect, without even talking to me, that I'll just say, "OK" and not even care about me or how I feel?
