Please give me advice on my heartache.....?

Me and my partner were together nearly 3 years and we have a baby together. Since havin our daughter he changed and things went down hill from there. Anyway he left me about 2 month ago and i cant cope with the pain. He keeps playing games with me by kissing me but then telling me we will neva get bk together. hes constantly giving me false hope. All i want is to be a family. I just keep showing myself up by always txting him and i know hes loving seeing me hurt like this, hes SO selfish! I know it would be so much easier not to see him for a while but its impossible because of our daughter. We moved away together so i have no1 to talk to and i feel so alone. Any advice would be so appreciated? thank you x
