<human>: Can you give me the gist of the text in a nutshell?

So I (M23) had been dating her (F21) for two years and she broke up with me as you can see from  
Went on a little stalk as is expected from post break up behaviour and I noticed, the guy that had taken advantage of her, she just started following him on Instagram. Why the fuck would she start following the guy who essentially raped her? So obviously assuming that she's still talking to him or lied to me, either way I'm absolutely furious and have gone from wanting to win her back to hating her guts. Now for the next step - How do I get over her? Any suggestions which don't involve spending ridiculous amounts on money on e.g. hookers or strippers would be greatly appreciated. Thanks.
