Am I over reacting?

My fiance works nights as a truck driver. This morning he decided to go pick up a truck he just bought and had his brother drive him. The area the truck was at is only an hour away so I figured they'd be back in about 3hrs and had explained that I had to be someplace before closing time and my fiance had our only car and I'm not allowed to drive alone right now due to health reasons so I needed him to hurry. He said OK but then took 5hrs to get the truck home. Once he was home he decided he didn't want to ride with me because he "didn't want to be in the sun anymore." Hello, you're in an air conditioned car, you don't even have to get out! So I scramble to get my daughter dressed and get the car cleaned up so I could take her with me and asked her father, who was originally going to keep her at my house, if he could ride with me. Like I really wanted to spend my afternoon with him instead of my fiance. So I barely make it where I had to go and while I was gone, my fiance job called to give me his route for the night because they couldn't get in touch with him. I figured he had fallen asleep but tried calling him myself and no answer. What really pissed me off was he was in fact awake when I got home and had just ignored the calls. Then when I tried talking to him (I didn't make a big deal of him ignoring calls) he said he was too tired to talk or spend time with me and immediately went to bed. Like wtf dude? Idk if he was really being a huge dick today or if it's me being 6 months pregnant and emotional but I was so upset I cried. He may have been tired when he got home but he almost made me late for my appointment and didn't even care and didn't want to even talk to me today. Not even a hug or kiss at any point. :(
