My Boyfriend

Hello Ladies.

I'm currently in a relationship with a guy who is much older than I am, but we connect on many different levels. Problem is he has an ex that's always writing him on Facebook trying to make small conversation, I've told him that I don't want them talking and yet he still talks to her (every now and then) and has recently given her his cellphone number. Also he has a baby mother and they talk a little too much for me, he says that they don't talk about "them" but how has each other been. Their daughter is 18. I've also told him I don't want them talking either, but yet she still calls him every morning & throughout the day. What should I do?
