I'm so hurt and upset with my dad

S • 💏💑😍
My dad and me haven't had really any relationship since he married my step mom. But I still come over here on his weekend or in the summer week. There's so much wrong with the situation here but that's not the point right now. My step mom's grand daughter is here to spend time with her grandma and my step mom's been working the whole time not seeing her granddaughter at all. Today my dad took the granddaughter hiking ( mind you he's always not in shape to do things like that when I ask him to) hiking is one of my favorite things to do which my dad knows. He never even asked me if I wanted to go. Didn't even tell me he was leaving just left. I was awake way before him so it's not that I was asleep. He never bothered to see if I wanted to go which was really hurtful to me. I want more than anything to do things like that with him and I try to do things with me but he wont. I'm to the point of tears. I just want to go back to my mom's and I'm seriously thinking about it later today.
