Girl…… you need to break this cycle. You have a child and this crazy on/off relationship you have with ex is just not healthy at all and your child is seeing all this. I am saying this as a mother myself. This person you claim to love is not healthy for you. He leads you on and showed he can’t be trusted. He is giving you all these signs not to let him be in your life. Ask yourself why are you letting him get in? Break it off and focus on you and your child.
