Why is my ex girlfriend trying to make me jealous?

I've posted before about this but after she broke up with me she told me that she has a nice selection of guys now but was only serious about one cuz he's a dazzling chap and she said shed cling to him as he's very attractive in alot of girls eyes so she then told me his dick size and that he likes her alot and stuff then she stops talking to me as we got into an argument I spent a few days apologising telling her I fucked up and I still have feelings for her and I'm sorry for the way I acted doesn't reply she just blocks me then a day later she sends me a pic of the dude she's talking to with his top off. I just don't get why? Why is she trying to make me jealous when she dumped me and she said she was over me why would you even bother to do this if your over them. I don't get it is it for a reaction does she still want my attention is it to rub it in my face like haha look what I have now does she want me to beg and crawl back to her? I just don't get it or see the point I was nothing but pleasant to her after the break up except for that argument and during the relationship she said I was the best boyfriend she's ever had. So why even attempt to make me jealous if she dumped me and was over me in like a week? It's just so stupid.

She broke down and cried to me over the phone and said she did all this to hurt me as I hurt her and that all these guys she's been talking to just wanted to talk to her as they know she's a flirt and she said my attention I gave her was different it was sincere and not fueled by lust and she realised that and stuff but she still likes the muscle guy cuz he has well muscles and stuff but she said she realises how much I actually loved her and how I appreciated her more then anyone else. I didn't know what to say so I said I'll have to think about it. Idk what to do? I love her she said she loves me still but there's that guy still....idk what to do now btw this is poopyhead I forgot my password DX

Well Poopy, looks like the ball's in your court now...you can either do two things...believe her and take it from there or ignore her totally. My two cents worth? ignore her....because she stills wants a guy with all 'outside' things, she's not looking at the 'inside' of a real man. She never has and probably never will. She can say all she wants now about how your love was sincere etc but the fact is, if she was genuine, she would never have put YOU through the last few weeks of hell. And so, as you're still asking the one question you've been asking all these weeks, the answer is, move on and start looking out for yourself.
