Am I just being paranoid?

So he tells me last night that he HAS to give this ex his number because of some court thing on the 7th. Which tells me that he's all ready given it to her and talking to her. When he talked to her on friday I was listening in and she didn't say anything about the 7th.  So I know he's talked to her since then. When the whole situation started with the other ex and the picture he told me that he'd rather be with with this ex then that ex, then she shows up!! What am I supposed to think about that? And now he's GOT to talk to her?! I mean come on. I don't want to have to deal with what I just went thru in December. Unfortunately I won't be able to "prove" anything via phone records untill our bill in June, since the billing all ready stopped before he started talking to her again. But then again I don't know if he gave her his verizon number or his prepaid. He's good at deleting things, so really I won't know.  At first I didn't care about this one, she hurt him so bad that I knew that nothing would ever happen again between them, but she told him she was sorry for everything she did to him. Which is great, an apology is always nice to hear, I just wonder if he thinks that because she said it, she meant it and will try and go back to her. I'm at the point now, where I don't even care. I love him very much and don't want to lose him, but I don't have the energy to fight for him anymore. He's going to do what HE wants, not whats good for our family. If that's the case then I'm gone.  I'm feeling so lost right now.
