I'm not trying to entertain my ex or anything but I'm trying my hardest to co parent because he wants to be involved. Today he messaged me and we started talking about the baby then I asked him how he's doing etc.. next thing he says to me is that I better not be having sex whilst pregnant with his baby and after I give birth he has to be the first person I have sex with just once. So I ask him, if he has a girlfriend and he told me he does and that it shouldn't bother me. I told him straight up I don't mess with other women's men and he told me to shh and wait for him. I told him no again, baring in mind he knows I have feelings for him still - he told me he won't leave his girl and that I can't hold that against him as an excuse to not sleep with him. I just didn't reply. I'm so upset right now. He knows I have feelings, I'm hurt, alone and stuck with his child. I'm just so lost right now...
