My girlfriend cheated on me?

Me an my ex dated for over 2yrs. she left me for some 18 yr old kid she was talking to online for a couple weeks. im 22 she is 20. Me an my family took her in an I bought her food clothes an etc. due to her hard background. she cheated an left me for this boy an moved in with him. She said he is a big church boy who loves his mom. Was wondering do cheaters get burnt? im hoping this guy burns her like she did me. Since then she lost her job, doesnt have a car b/c she is afraid of driving. lost her phone an is in debt which will screw her future credit.
