I don’t feel good after FaceTiming him

I felt as if he felt obligated to FaceTime me. He was busy doing work for most of the call. I didn’t try to talk to him because I didn’t want to distract him from his work. I just feel bad because I feel like he didn’t really want to FaceTime with me. I’m not sure why he’d want to call with me but then pay me no attention. I can’t help but feel sh**ty and upset. I would have been okay if he told me that he was going to do work and we could FaceTime tomorrow
