for some context, i have a friend i am really close with. we talk/text daily, hang out a couple times a month (we live sorta far away), and play video games together. i normally think everything is fine and we are both enjoying each other’s company. over the past month he’s been sort of distant. we made plans to hang out, and he canceled. that’s ok. then we make plans the next week and he cancels again saying he “needed time alone”, but then was hanging out with other people? to be fair it was his cousin but they hang out all the time. and when i said i thought he needed time alone he had some reason why he HAD to see her and she “forced him”. then he’s sending pictures of them together, or facetiming me. what is that? then the next day he’s hanging out with her again and a couple other people. facetiming me while they’re together, sending pics, etc. i’m so confused. is this intentional? is he just not realizing that it’s hurtful? 
i tried to ignore it but now i’m thinking he just doesn’t want to hang out with me. i asked to reschedule for next week, “no”. i text him, he answers very dryly or sarcastic(?) if he does at all. i ask to play games, “maybe”. basically everything he says no or maybe to.
he told me if i’m ever feeling confused or upset with something he does, to tell him and we’ll talk. i told him i was feeling like i was just bothering him and he doesn’t want to spend time with me, and all he says is “no don’t worry”. i said sorry i am overthinking, he says “don’t be sorry and don’t worry”. how can i not worry when he’s still being cold? i understand everyone might need time away from a certain person or time alone, and people have their own issues, but this feels so directed at me. it feels like i did something wrong or made him bored so he wants to push me away. 
i’m trying to just leave him alone because i’m sure (not entirely lol) everything will go back to normal in time. but it’s like an itch on my brain that won’t go away. sometimes i really can’t tell if i’m overthinking or if my thoughts are justified, but either way it’s making me sad. am i overreacting or is he pushing me away? sorry this is so long.
