<human>: Can you give me a shortened version of the text?

Note: this is an x-post from r/relationships. Hoping to get more responses here!

Backstory: we were close friends for years and talked constantly even after we moved to different cities. After my boyfriend and I broke up we started testing the waters and talked more romantically.

Things were going really awesome, but then we got into different grad schools and it was like a switch flipped overnight. Literally a COMPLETE 180. He said he didn't want to ruin our chances at something long term by going long distance (not his cup of tea, and that's fine) and wanted to limit our interactions from talking all day in case feelings progressed too far. And that when we're done maybe we could try again. Okay, sure. Really, I was honestly just concerned that it was going to affect our friendship but he assured me it wouldn't, even though he also added that we're now more than friends, but not boy/girlfriend. Oooookay.

It's been a few weeks and it definitely has affected our original relationship. We don't really talk anymore, and when we do it's one word responses. Or he'll ask a question and give me no response when I answer. Completely the opposite of what our years-long friendship was up to a few weeks ago but he denies any change. On my end I've made it clear from the start I'm completely fine with reverting back to talking as we were before, just as friends. He said he was too, but there is definitely a change from what we had before and it's just so upsetting. It's like the situation erased one of my best friends from existence.

Does anyone have any thoughts on what's going on here? Maybe since I'm no longer an "option", the entire friendship isn't worth investing in to him anymore? I really valued our friendship and he claimed he really does as well. Or maybe a few weeks just isn't enough time for things to bounce back?
<bot>: Deciding against a long distance relationship might have ruined my friendship but I don't know. Pls advise. I miss my friend so much.
