Feeling weird

Hi girls,I’m not sure if someone here can relate or can give me some sort of advice.

I had a hookup a little bit ago with one of my closest friends and I think that’s where things went wrong. We have so much trust and I just feel really safe around him,I had never had this level of trust or friendship the way I do with him. Thing started off as normal,we were drinking and it got to the point where we were cuddling on the sofa and I started to play with his hair,he was basically with his face on my neck and I thought nothing of it,he then tried to get handsy and I kinda went along with it but I wasn’t feeling sure because he’s my best friend so I didn’t wanted things to get awkward within us but I went along with it because I lowkey wanted to,anyway whatever had to happen happened and ever since I’ve been feeling weird about it,like something deep down on my head is telling me it wasn’t right and I kinda feel betrayed,like I did wanted to but I just didn’t think it would ever happen so now that it did it has made me wonder if that was the plan all along,we haven’t talked about it ever since it happened and we just moved on as if nothing changed (which I think it’s good,but I’m just feeling weird about it)

Idk if it’s just me that’s making it weird or if the reason I feel it wasn’t right is because I think that was his intention all along and I feel betrayed.

Thank you so much for reading.
