OK. Telling you right now, while everyone is capable of change, IT IS NOT LIKELY. No person who loves another would tell them they love them and want to be with them without their child. That's selfishness, not love.
You can't convince him to want the baby. Period. He is capable of making his own decisions and right now that doesn't include a child.
You need to draw the line. It's going to suck, trust me. But you need to tell him you are keeping the baby, that you and the baby are a package and if he doesn't want it and want to treat you well and be a stand up father, then someone else will. BECAUSE IT'S TRUE.
You love him. That's okay. But you need to love the baby, and yourself, more than to let yourself be emotionally abused like that. Right now the baby feels everything that you feel. The stress will hurt you AND the baby. He may love you, but he admits he's not ready for a baby. Honestly, that's good of him. Better that you figure it out now than when the baby is here and he walks out on both of you. Better for your baby not to know him then to have memories or him leaving you guys!
Your first concern should be your child and how to take care of it. Period. I ended up wasting all of my pregnancy being concerned about my relationship with the father and I missed out on all the joys of being pregnant. It's one of my biggest regrets now. Don't make the same mistake. If it's meant to be, he'll come around. You have nine months for him to grow up. Step away from the situation and maybe he'll figure himself out and come back. If he doesn't, then it's okay. You'll make it through it no matter what.
