My partner and I have been together for 4 years. We have been having a ldr for about 4 months due to his job. He was supposed to be coming to spend Christmas with my family but my dad and sister have covid. He has to go for an interview for a visa in January so he is saying he isn't going to come for Christmas as he does not want to catch COVID because of this. I just feel so upset I won't be spending Christmas with him and feel like he is cares more about going to the US then being with me. Am I overreacting?
