I need help....

My boyfriend is really blowing me. He's making these impulsive decision and not taking me nor his family into consideration. Two days ago he lied to me over something so stupid. He went to Mc Donalds and he got us both food. We are both dieting so we make an effort not to get fries. He said to my face he didn't get them. Next thing I know I look in the bag and there they were.. THE FRIES??!! he then proceeded to tell me oh it was a mistake on their part why they were there. I'm like do I look like boo boo the fool??? He finally admitted that he got them he was just ashamed and knew hexwaant supposed to get them so he lied. I don't understand why he had to be an idiot and not tell me the truth. If your gonna lie about something so simple then what ru gonna do about the bigger things. Then this morning at 12am he decided ”oh I'm feeling restless let me go for a run” AT 12AM??? Are you serious?? U clearly don't care about your safety at that point. You couldn't find something else to do?? Just stupid... Am I overreacting??? can someone help me I'm just so over it. Why should I care about you or this relationship when you clearly don't.
