Just a rant

So tonight I told my bf I couldn't come over like planned bc I didn't have a babysitter for my 2 year old and he said he was to tired to come over but about 15 minutes ago he called me and said he was going to his friends house to look at his truck (my bf is mechanically inclined).. I was like really? I thought you were tired 🤷‍♀️ he just said I am. It's literally 11pm. I know I'm probably being a Brat but how you gonna tell me you're to tired to come to my house but then go to someone's house to look at their vehicle in the middle of the night? I told him that's kind of messed up that he couldn't come over here but can go over there..
