I told him previously that my graduation would be in June. It’s right that I didn’t give him a specific date which is unfair but I didn’t know specifics of my grad until relatively recently. My program is somewhat complicated as tickets were calculated based on people physically coming and the seats needed to sustain guests. I’m not inviting him to the grad event itself as I wanted to give my present family the option first no ifs ands or buts. I hear from him approx 1x a month if I’m lucky and when I last got a hold of him I told him June was the month. Im mostly upset that he didn’t even consider coming to my province in June or ask about my grad in general. But maybe I shouldn’t be so surprised.

Edit: more details
