My child’s father was in the picture the first 4 months and left me for the last two months I’ve been doing everything on my own and he texts me and FaceTimes me and tells me he wants us and that I’m going to see him but than turns around and changes the script. So today I told him it’s either you stay with me and we work it out or you leave me and you leave for good I just want the best for me and my unborn daughter but him playing with my emotions while pregnant is not cool I do miss him and love him but I’m 6 months pregnant and my hormones are all over the place as of now. So did I do the right thing by saying that to him?
