Boyfriend broke his promises and stayed out late. Do I have the right to be annoyed?

I'll try to be quick..

He's known for choosing his friends over me. Today he's staying at his parents house as it was his mum's birthday and I had to stay at home as I'm ill.

anyway, he said he'll go see his friend just to give him his xmas card and say hi. He's taking his dad's new 4x4 truck which he never drove before..I wasnt happy about it so I called him and asked if he's taking it and said yes. I said I wouldnt want him to as im worried as it's night time and he drives through small roads. He said he'll be fine so I asked him to be back at 10 (I meant 9 but read the clock wrong) but then did say about 5times. "In 45min" and he repeated and said he promises he will. Then when he got there (9:15) he said he's going out with the guys...aftr I reminded him he promised he said he'll drive carefully. I told him he broke a promise and im just turning my phone off. He kept textinh sorry. ...im annoyed as he never keeps promises and I worry like hell!!!!!! And I'm 3months pregnant.
