My unborns dad and I haven't been talking much lately, mainly because I feel like all I do is get on his nerves. (We aren't together, used to be, started talking again and I got pregnant, and we didn't end up getting back together) well he text me today telling me how he loves me and wants to get his life better together for me and his son. This makes me feel like there's hope. He wants to come get me when I get home from work, but when I tell him I have to stay at my mom's because I have to go to the doctor in the morning he says he gives up.. I don't even know what to do anymore. I love him so much, and want nothing more than my son to have his father around. :(
