<human>: My SO [27/m] of 1.5 years and I [24/f] recently broke up because I had some visa issues and had to leave the country.

We decided not to pursue an LDR because he had done it before and did not want to go through that again, and I knew that I woudn't have the emotional maturity to maintain a healthy LDR.
Also, we are each currently in the process of starting a new
 life--me coming home and wanting to travel for a while, and him having just relocated to a new city.
Neither of us has no idea where we will be in the next few years.

The last few months of our relationship was basically a count-down towards our expiration date, but we had a lot of fun and spent *a lot* of time together. We got into fights sometimes (mostly because of me, I get jealous...) but I know we loved each other. We both cried when we said goodbye.

It's been a week since I left, and we've been talking everyday and acting pretty much the same way we had been before I left. But, this past week has also made me feel incredibly depressed. I still can't seem to face the idea that we are no longer together and might *never* be together again. That our daily chats and texts are eventually going to dwindle until they become non-existent. That we might one day move on and find other people to date. It's inevitable and how life happens...I understand the concept, but am having a hard time internalizing it.
I'm scared that our relationship will become something of the past.

 
I wish I could still be with him right now, but I know it's not the right time. It was bad timing, and there's nothing I can do about it....BUT IT MAKES ME SO SAD. I don't want to move on at all, and, very selfishly, I don't want him to either.
I miss him so much and am too scared to cut contact with him. I have become so dependent... I'm terrified and have no idea how to deal with the pain.

How can I get through this?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Just ended relationship due to visa complications, still very much in love, and terrified of the inevitable process of having to move on.
