<human>: Give me the gist of the text in a nutshell

I got married last May. We had intended on a big, Alaskan, backyard wedding, but I found out last minute that a lot of my family couldn't make the trip, including my BioDad who was living in North Carolina at the time. Airfare to Alaska is often outrageous- So we decided to all go to Vegas. It was fun. Nothing fancy, but super fun. My in-laws rock!

Fast forward 1 week. I had just sent him a bunch of photos from the ceremony and the reception and was then talking on the phone with my dad. I could hear him clicking through the pictures as I heard a familiar hiccup in his voice. He was crying. Well, trying not to cry. After some prying, I finally got him to reveal that my mom had told him not to come to our wedding because my stepdad "wouldn't have paid for anything" and would've "ruined heymandarae's special day" if he showed up. 
I was speechless. This was absolutely not true. I assured him of this and he seemed to already know. My stepdad can be a bit uptight, but he has a huge heart and would never have done such a thing. Dad even mentioned that he would've just shown up; but he didn't want to chance ruining my special day, in case my mom knew something that he didn't.

I was pissed, so I asked my stepdad. She lied. She didn't want to deal with the confrontation of having my Dad see her failed marriage. (oh btw, my mom is extremely verbally abusive towards my stepdad and still insists that he is the horrible, annoying one) She lied to keep her image up- the image that she is the victim. My stepdad and I agreed to not tell my mom that we had discussed it. 

My dad had a heart attack and wrecked his truck one month later. He died and I now hate her for all of the things she prevented us from having on our own.
<bot>: Mom is a jerk to BioDad. BioDad feels unwanted at only daughter's wedding so doesn't go. BioDad dies tragically one month later. Only daughter now hates Mom.
