I just don't want to be a burden to anyone

*I would love to hear what people have to say but mostly I just have to tell someone that will listen and chooses to hear my story*

So my parents never really had a great relationship from the start. They were friends with benefits. My father wanted to be a bachelor all of his life. My mother a hopeless romantic been in abusive relationships, had kids, and got away from the abuse. My mother fell hard for my dad and he just couldn't give her those feelings back. She lied about having her tubes tied and he knew she did but he didn't care and they created me 22 years ago because he said he would never marry her and she just had to have a piece of something that was him. She told him she would raise me by herself and he didn't have to stay but he felt obligated. They have been lifelong partners or together I guess since. He adopted my sister. They bought vehicles and a house and whatnot together. Best part is, he hasn't ever not cheated on my mother no matter how hard she tries to keep him happy. Always with the same woman. First time she caught him he was in a bar one night with his side woman on his lap and I remember the fight they had that night. I had to stay with my grandparents for a week for them to figure it out and pick up all the glass off of the floor. The second time I went to do a research paper on the computer and he left his email open with all of his dirty sex conversations to her open. I forwarded them to my mom. He was so mad at me for telling her he didn't talk to me for at two years unless it was something spiteful. This week my mom found him out the third time because she was cleaning around his phone on the charger and it turned on to show a text that said he loved her. Both of my parents have issues, don't get me wrong. But I've always felt like my dad has despised me and when they finally told me how I was conceived it really only got worse. I'm married now and pregnant, I have no friends because we all moved away or they dropped me because I got pregnant and married when they wanted to party. My siblings and I don't talk because of many different reasons. My brother is a lot older than me and a truck driver so we never see each other. My oldest sister has mental problems and is way older than me. My closest age gap sister sees how messed up everything is and distances herself from the whole family. But I try to love them all regardless though it gets very hard. I love my husband but my family is really messed up and he never really knows what to do or say. I'm stuck dealing with it all on my own but the older I get the more harsh everything seems and it's hard to feel so much like a burden to everyone. My mom asks me for advice about my father and I truly believe they should break it off. There isn't trust, respect, or communication. Neither one of them wants to see professional help to get to the root of their problems so I don't think they will work out their problems at all. But she wont stop giving him chances and he is never going to change. Worst part, they are basically killing themselves since this last time. My mom has increased her smoking by so much that she smoked two whole packs of cigarettes in less than six hours. My father has Marfan's and it's affected his aortic valve so much he has a pace maker. He is cancelling his insurance and doctor's appointments because he doesn't want to live anymore and just wants to see his granddaughter be born and be done with it is what he said. So I'm just trying to really hard to keep myself together and I feel like my thought process isn't currently the best because I have so many emotions running wild on top of other situations going on with my family, "friends", pregnancy, and in-laws. I feel like I should figure it out on my own that way I don't bother anyone but I don't know how and no one ever asks me how I'm doing so I never say because I guess they don't actually want to know.
