Feeling betrayed and hurt

My boyfriend planned 2 days ago to go on a date with me , the next day bailed out without saying sorry. He asked yesterday if he could see me today I told him I’d be available anytime, we were set and then this morning it was like he forgot about the fact we were supposed to see eachother today, he never mentioned it and he had a family reunion thing going on which I didn’t bug him about, still not remembering that we both planned to see eachother today ot after. He asked me when he got back home “Are you doing anything tomorrow?”. Without saying sorry for not telling me that he had something going on in the morning and that he was running late. I told him I’m not sure because I might be busy tomorrow and today was the only time I was free all day. He said okay and told me he was too busy today with family stuff and he’s tired. Little did I know he cancelled for last minute plans to go out with his friends tonight behind my back. I’m hurt because he’d always promise to see me, he never does and eventually bails out on me for his friends...Shows how interested he really is in me
