I feel like he would've been slightly annoyed if I asked to come over too, but it probably would've been fine overall. I can't remember if I was busy that day but there was a probably a good reason he didn't invite me. So that's why I think I was being unreasonable about the whole thing. Regardless, I still have those uneasy feelings and I have no idea how to make them go away :/ Other friends have told me my feelings are valid though so I really can't tell if I'm the wrong or not.
