Time to rant. FYI kinda long

You told me you wanted always and forever. You told me that you would always be there for me. You made me believe that this time when someone said it they meant it. Then you cheated and even went as far as taking money out of the house to pay for transport for said cheating. You continued to use me and lead me on after I forgave you. I let you use my car for work while I would watch your daughter without thinking twice about you never asking because I got attached to not only you but her as well. I treated her as my own even though she wasn't. You've refused to acknowledge issues in the relationship or would somehow try to turn the blame around onto me and that it was my fault when yet you were the one only thinking of yourself. I'm glad that you started an argument about your daughter and how your her father and she's no concern of mine even though 90% of everything she has at the house is because of me. It opened my eyes and showed me how little respect you actually had for me and how I was just around for your benefit. That's when I had to call it to an end it showed that no matter what I did it would never be appreciated but only took for granted like it had been for the last year and a half. You became very toxic to me and with all the stress and hurt you've caused something had to change so I initiated the break up. Only to realize after breaking it off that I hadn't had my period in 2 months but pushed it off on being from the stress you've caused. I had to get out for a bit and I reconnected with some friends and told them everything it felt so good to finally get things off my chest and be able to talk to someone about it all since you never would talk. Told them about the period thing and they made me test and it came back positive. It wasnt just you that failed me but birth control too. I came back to the house to tell you about it and all you do is walk away and tell me "just go" but you'll be the one leaving your the one who's name is being taken off the lease since I was the one who busted my ass to make the place happen with working 6 days a week and securing the place for us to move only to find out you were cheating because "you didn't think I was happy"... I can't wait for you to get out I'm more then ready to be a single parent on my own I've been pretty much doing it with your daughter for over a year while you were out doing God knows what with God only knows who. Will it be rough? Yes will it be challenging? Yes but you became way to toxic to me and with me being pregnant now I don't need the unnecessary stress that comes along with it. You'd always say how you wanted to get married and you had even started talking about wedding details and everything, buy a house with a yard and have kids of our own one day. Guess one thing that was ever talked about is coming true and that is the kid part just sad to say you won't be around for it and that's a decision I had to make. You're not ready to be a father again even with the daughter you already have from a previous relationship you don't look out for her best interests. I had to even get you to spend time with her when I came into the picture vs you having the tv doing the babysitting on the days you had her. I was the one getting her the things she needed only to be told by you she wasn't my concern that she was yours. Now you can go live your life the way you want and have been without thinking of those you effect and without your 2 kids because I don't just have to think for myself anymore but the kid growing inside me. And yes I did fill in your daughter's mom on EVERYTHING. And once she gets her place set up she made her decision as well for the well being of your daughter. I Hope your happy with your choices and losing 2 of the "most important" things in your life. But you've left both of us no choice in the matter regarding any of it and still continue to not communicate with either party. Whereas your daughter will still know her half sibling and her mom already discussed about it all and we're not going to let the kids suffer because of their irresponsible father
