So we are together for quiet long...I was late at our date the other day,I sent him message saying that I'll be late and that I couldn't speak I was washing my hair and than my mum called me to help her to take some stuff in the house so I lost knowlege about tame ..He called me 3times and since I didn't answer, he got back to his home 1/2hour away by car and when I contacted him asked him if he is willing to come back he said no,and that he is tierd since he is been working since 3oclock in the morning till night.And to tell him when will I be able to see him again,I said at weekend and he said Ok,see you next weekend.
I called him like 3times and sent him sorry message at saturday and he hasn't respond anything since.(is thusday at my place now)
I was thinking to let thinks to calm  down and call him at friday to see what will he say....
I'm not shure if he broke up with me at silent way,or what...
I know he has too many problems these days and too much buisness to do,so I'm not shure what to think...
What would  you do?
