<human>: Can you provide a brief overview of the text?

So, a little background. Boyfriend and I have only been dating for about 3 and a half months. He and his ex only broke up a few weeks before we started dating. I'd say they dated for somewhere between 9 months to a year before splitting. She broke up with him. **He's 32 and I'm 22.** No idea on age of his ex.

Ever since we started going out she has been texting and ringing him. Before she knew we were dating she was constantly asking to meet up with him to talk and, presumably, try to get back together. After she found out about me, she turned to being horrible about me, about him, about our relationship. She seems to believe that he and I slept together before they broke up so has decided I'm a horrible whore.

Anyway, boyfriend and I were having problems so we took a break for about a week and a bit between the 25th of June and 4th July (dating it makes it less confusing). Two days before he and I met up and decided to get back together, he met up with her. He assures me that he met up with her just to talk as he was feeling very down and lonely. She was apparently very sympathetic but then tried to kiss him. He told her he wasn't interested, she flipped out and fucked off.

Now she is back to texting him INCESSANTLY. He only tells me when he KNOWS I've seen her name pop up on his phone and otherwise won't mention it. I can't be certain if he's responding to her though he has said he's not. 

I'm just wondering what on earth I can or should do. It's been four months since they broke up and she has never eased up on the harassment. What's more, it is evident that she wants to get back with him and it makes me incredibly uncomfortable that she is contacting him so much. I'm at my wit's end about it all. I know he loves me but I feel he still has residual feelings for her and might not be being entirely honest with me about what's happening.
<bot>: Boyfriend's ex has been persistently ringing and texting him since we started going out. It doesn't seem to be getting better. He says he doesn't respond, not sure I can believe him.
