Hormones ?

I get mad at my SO for a lot of things. But today I got really upset because he decided to go dirt bike riding with his friends instead of hanging out with me. I haven't spent a whole day with him for almost 2 weeks and just wanted to hang out with him today. He works Monday too. Ugh maybe I'm over reacting. I just miss him and hate being alone all the time ? anyone else get like this?
