I (28m) have a long term friendship. He is 38. Over the past few weeks, things have felt really off between us. I help him move out and once bought him cigarettes, but since then I have not been to his new place. I dont even know his new couch. About two weeks ago he had a BBQ and invited people, I thought it was just his girlfriends family, so I didnt think it was appropriate to come. However I found out that other people from our shared friend group were also invited which means I was intentionally left out. The day before yesterday we met at a birthday party. I stayed just for an hour cause I arrived late and was tired. I said goodbye early and he asked why I was leaving so early. I said I wanted to go home and relax and he responded with: you and your home, always going home. This felt weird but after this I leaved. Yesterday we played a game with three other people. In front of me he invited one of them to come over for the next day, but not me. I found that very strange. Then the day after I ran into him at the supermarket with two other people. It was clear that these two people would also be there. So he again, not invited me. In the past three weeks I invited him twice and he came both times wih other friends. Now a friend told me that he is disappointed because he thinks I've avoiding him and even suspects I might have depression since I often declined his invitiations. He is like okay he declined often, Im not asking anymore. In reality I was just focusing on studying for exams and had a gaming phase after that. What frustrates me is that instead of talking to me directly about how he feels, he's been acting distant and excluding me to ''punish'' me. To me this is childish and immature. If he's disappointed in me, isn't is basic that he should come to me and talk about it? Officially I didn't know anything was wrong because he never communicated with me directly. Until yesterday at the supermarket I thought everything was fine because sometimes friends have more or less contact and thats normal but then I realized something was off. I've been usually been the one to make the first move and I dont think it should always be my responsibility. So AITA for not reaching out first after he started acting this way and excluding me? Edit: It was not his birthday party
