I'm a 32 year old who encountered some mild bullying by a roommate who I thought was my friend at the time. Just some name calling and invasion of personal space to begin with. I snapped at him once during my third last week rooming with him to which he apologized, but on the very last day was when he was the most aggressive. He called me stupid when we played one last round of league, kind of horsed around with me briefly like he was a fighting game character and put his hand on my shoulder with a condescending smirk when he saw me off. This was all on top of me struggling with a very stressful job but quitting it on that final day when I moved out.

I didn't think much of it right at the time, but then I realized he had kind of been bullying me for the last three or four weeks I was rooming with him. Now I'm filled with anger and shame because I was 29 and allowed someone to act like this to me without having established firm boundaries. It's been two years and I can't shake these feelings of shame and anger, I'm pretty obsessed with how he treated me and keep replaying that day over and over again in my head. Am I overthinking this situation?
