Opinions pls

Three days ago my bf of three years invited me over ( were moving in together in two months)I just finished making him lunch and cleaned the kitchen and while laying down for bed he showed me a text of his cousin saying theirs mom really needed him that they have bottle. It was 130 am and he walked out the house right after . He never came back home. I Left for work at 10 am . I took all my things from his house and said.I was done.We work together and he never showed up for work.This is the third time he has done this and he knows I feel like its disrespectful . He just keeps texting me saying he loves me and he wont do it again that he doesnt want me to leave him. Ive stood my ground since.Am I overreacting? * Their was no emergency they just wanted him to go over and drink with him* I agree with what you said about boundaries, I thinks just wrong to leave your spouse in the middle of the night while theyre spending the night and never come back. If hes doing it now what makes you think hes not going to continue to do it. Ive spoken to him enough times , how much more communication does their need to be to understand I find it disrespectful. I dont mind him going out but come home at some point.
