<human>: I'm [24M] finding it hard to change my opinion of my friend [23M]. Since the beginning of the year he's done some things that I consider to be very rude. He's publically insulted and embarrassed me on the bus, he's invited friends out for dinner and never spoke to them (or anyone else at the table) and He's gone entire outings without speaking to me or anyone else except his girlfriend. Those are just the big things, he's always on his phone (looking at twitter), he doesn't seem interested in anyone's life or what they've been doing and never tells anything about his life even if we ask him (I didn't know he was dating for months after and claimed it was obvious when I told him I didn't know).

Despite all this he continues to arrange things for the group of us to hang out, but shows no interest in hanging out after we're all together. We've been best friends for 10 years and since the beginning of the year it's gone downhill in the past two months. I just don't know what to do or how to act. How can I put aside my opinions and just be friends again?

Can you provide a brief overview of the text?
<bot>: My friend has ignored me when we hang out, I don't know how I can get over it and just want to be friends again.
