My SO said that he would take me to movies last night, he promised this on Wednesday. This morning I called him to ask what time I would see him, he then tells me that he has plans to go to a BBQ but it is not confirmed and he will let me know. I told him that it was rude to do that and he cannot keep me as a back up plan. I then went ahead and changed my plans. He then calls me at around 14.00 and tells me that he has cancelled the BBQ plans on this guys voicemail and he will come to me. I told him that I had already made other plans. He got really angry telling me that I should not have jumped the gun and should have just waited to hear. I am put out by this because it is as if he wants me to sit around and wait for him to tell me what I will be doing with my life. His reaction to me was horrible. He was shouting and he even smses me to fuck off. I am not overly upset because I won't let a man treat me badly again and have sort of detached myself from this. I changed my plans so that I could see him this weekend and now he tells me he won't be seeing me at all and that we are now over. The problem is that we are going away on holiday together on Tuesday for 2 weeks. So I just want to find out if how I reacted was wrong? I changed my plans with my friend from Saturday to tonight because he had changed the movie plans with me. I am so confused as to why he is so angry with me. I did not shout or yell at him for changing plans and keeping me as a back up, I simply changed my plans and when he called me to tell me that he has cancelled his plans I told him I have arrangements but he must feel free to join me, to which he responded that he will not and he will not see me this weekend. I am confused, what do you all think?
