Search Results: how to get your ex boyfriend back

So basically my boyfriend and I had been broken up, and he hung out with a female friend he knew from high school (he's 26) a few times and when we got back together I saw messages from her from when he was single asking him if he wants to do things like have a "slumber party," to which he gave some weird excuse and then to asking if he wanted to have a "pajama party" to which he replied yes. Other than that she was the only person to flirt, calling him cute and fishing for compliments.
But not once had he ever really flirted back. He claimed he denied her flirting.

i mention that they can still hang out but I'd like to meet her first. So he gives me permission to ask her and when I do she texts my boyfriend calling me crazy. He tells her he knew about me hitting her up and says that wasn't cool.. I tell him I definitely don't want them hanging out alone now.

so then not long after that she calls him and asks him to hang out. He's on the phone with her and I can hear her, she sounds flirty without having to say much. He says they can grab lunch and they hang up. I tell him I don't want that to happen but that he could do what he wanted and he sees how I felt and says he's not. That was the last time she contacted him.. I wonder if
they slept together, do u think so?
