Would you let him bring his girlfriend around your newborn?

(This is the fixed version because i made a typo and couldnt go back .)

My ex SO cheated on me during my pregnancy and left me and replaced me in a damn day. Now im beyond heartbroken and he used to emotionally abuse me and was physical a few times and we been together 3 years. Now his new gf wasnt happy i was pregnant but i dont wan him taking this baby and thinking he is gunna let that bitch around my baby like she knew he was with someone but once u found out i was pregnant u still stayed like i feel like shes a home-wrecking bitch. Id take him back if i could regardless what we went thru because im in alot of pain. But I refuse for her to b around my daughter or even see photos of her if I could. I should tell him he could come c her or spend time with her without his girlfriend or its not happening i swear.
