Throwaway for reasons.
I know it's nasty and bad but please hear me out. 
We started dating 2 years ago and it was all fun at first. But when my mother found her in my bed she through us out and we'll we've been together ever since. The whole time of the relationship i have worked my ass off to provide for her. A year ago I took a job in the logistics industry working 12 hour days 6 days a week for little pay. I come home and cook dinner and drive her around and buy the booze and dope. In March we found out she was pregnant and by then we had already been on the rocks. I was a child raised by a single mom so I knew it would be bad if I left but I just can't do it. 
She doesn't do her part. I work six days a week and come home and make dinner every night and she can hardly find the time to wash my clothes. Mind you she always has clean clothes and what ever she needs in clean while I go wearing the same dirty shit over and over. I have tried to buy new clothes but she always "looses" them some how. I have spent around 600$ on clothes that are now lost. The house we live in is old and always a mess. I tried to help her keep up and get her started with the cleaning but it always just gets back to a pig stye. 
When ever I try to talk to her about doing better about her half of the deal she always throws my mistakes in my face and says my feelings aren't valid. 
I don't get what I need out of life from her and I am far too tired to do anything. For the past few months Ive been drinking my self to sleep every night and I wake up dreading the day she pops out the kid. She is not for to be a mother nor can she keep a house. She always rubs it in my face that I did this and that I am going to pay for it and her. 
It kills me
I have some money saved up. Enough for one good last burn. I plan on going out of town sometime in August and just putting all my money up my nose or in my arm for good. I am deeply troubled by the past 2 years of my life and wish everyday that I never met her. But that's life.
