Im confuse with my ex plz help?

like you said she has good morals so i dont think she will bring in another man into ur apartment. If she wants to move in with you i think that she wants to make the relationship work for the sake of your baby but if shes showing no signs of interest in you then maybe you should tell her that you want your relationship to work for the sake of your baby and that you will take care of her and just keep trying bcoz you never know what can happen if you really love her then dont give up on her keep trying
