At my wits end (long!!)

this is a long story but here goes. I need help!!! My daughter father and I split a few years ago. I felt he wouldn't listen to how I felt about anything and he felt I didn't want him. I simply asked to move slow with me. he first said he understood but he WAS a hopeless romantic and thought I'd cave if he just showed me he loved me. we've always loved each other but he is very pushy and when he decides something should be a certain way he doesn't let go. he left. he started dating someone and they broke up several times because she couldn't handle that he loved me. don't blame her. this woman is a puck Sally to say the least. shes stalked me, harassed him, on and on. he and I started seeing each other again. little did I know he was sleeping with her too. She said she was on birth control and surprise got pregnant. he tried to work it out with her but she went even more crazy. at 26 weeks she would text him saying she was aborting. on and on. does my dumb ass back away. no...i let my heart lead me. I've supported him in this process even buying his stuff for the nursery. well it gets so much better. I am 11 weeks pregnant. I am stressed beyond belief. I know he is too but he's gone from "I want you and i" to I"i have my own shit" I'm all of a sudden a pain because I am hurt. he won't talk to me about anything and says he doesnt know what he wants. he says he is about to have 2 babies and I have to understand. forget that I am going to be a single mom to 4. I can't do this in my own. I also want to add that I had our daughter early due to stress. I literally had a 10% chance of making it. I feel invalid, unimportant, and so alone. I am so stressed I feel this pregnancy will end like my last. I couldn't work due to our daughters needs for 2 years. I am so scared if I have another like her I won't be able to work amd i alr3ady struggle. and thats if i make it this time. i dobt know what to do or where to turn. i cant even announce my pregnancy because he is afraid she will find out. i am losing weight now, daily panic attacks. i just want to be happy and healthy. i want us to work so badly but he isn't helping me or any of my needs at all. I can't even tell him how I feel without him yelling at me. I dont suffer fro. depression but i have beem extremely depressed. i really need help and support!!!
