Why does my ex's new girlfriend keep calling me and sent me a text?

Several questions you need to ask yourself. Are you willing to buy his beer and weed? I think not since you have a young girl to be responsible for first. You should not want her to live around weed or in a drunken environment. This new girlfriend can not keep him from seeing his daughter or you for that matter unless it is what he wants. She can not keep him from calling to check on his daughter. He has some real issues and needs to "man up". He is keeping you on the ready line just in case it does not work with the new girl. I suspect he already realizes it is a short term fun time thing going on. He is saying loving things to you but still with her? Is that not a little strange. Maybe not if he calculates the cost of child support vs coming back and supporting only one household. He does not love her yet but loves the drink, smoke and hot sex, yeah the hot sex. When it ends he will try to get back with you. She is antagonizing you. Do not let her cause you to lose you cool! You seem to handle that well. My thought: You have the DNA results it is time to move on the court date for child support, etc. Forget ever going back to him he is a looser. The child will be better off for you to find a real man and they are out there that will embrace the child. Since the new girl calls, call her often talking about how cute the baby is and the things she is doing just like you would want to share with him. Trust me he will get it!
