Advice

Hey ladies, so I have a quick situation I need some advice on! So I am having some boyfriend problems at the moment. He has been EXTREMELY busy with his real estate work. Plus he has a side job, night job. So,i don't get to see him a ton. Last week he promised a full day with no work, and he would tell all of his clients that he is off that day and won't be able to be available. Yesterday he took me to our local zoo and wlhe promised me a day without any work. Well, that changed. Half way through the drive there, text messages, calls from clients. I'm eating in the car, talking with him. And he interupts to ask me to read off the message ABOUT WORK. I tell him no. And he got really mad and told,me,i was overreacting. So I read it off. He told me that that would be all,of it for the day. Well. Again he lied. When we got to the zoo, he was walking and reading messages. And talking about work. When we say down for lunch he said he was going to reply to some more and I said no. But he did anyways. And then he told me no more. Until we got home and he was on the phone talking to clients and other agents. And today I'm upset about it but he thinks I'm overreacting. I don't know how to respond. All he said is that "I can't even reply to someone? Are you crazy? This deal is very important, I can't lose it Kim!" I want to cry. He promised me a day without it and he lied. Now he's upset with me... How do I talk to him about this?
