My best guy friend of 8 years has suddenly just cut me off. Everything was normal until 1 month ago. We went to a movie one night, and at the end he discussed making plans during the coming week. So I texted him later that week when I hadn't heard from him and no reply. Days later I texted him a cute cat picture I found online and 2 days later I get an "LOL cute" reply. I try to ask him about his weekend and he gives me a super short reply. Over the coming weeks I try to make plans or just conversation and I literally get no reply or just 1 or 2 word answers. Not like him at all - he would always make conversation or if he couldn't do something he would suggest other times for us to get together.
About 3 months ago he got a long distance gf but that didn't affect our friendship. He still invited me out to drinks, to go to movies, making other plans, etc. But now, nothing. It's so weird and I don't have answers because I can't get more than a 3 word text out of him. From what I can see on social media, he MAY have broken up with his long distance gf (or been dumped, one of the two), but I'm not totally sure. There were just a lot of signs. At first I thought maybe he was going through a tough time so I gave him the benefit of the doubt, but it's been a month now! I texted him asking if he wanted to hang out today, and 9 hours later he says "Hey, I'm working today." And that's it. I just want to know what I did wrong and to get some closure.
Any thoughts on his behavior??
