Move on Cat and forget about her. No woman is worth obsessing over..........
I agree with everybody else bro... Just move on. Don't spend any[ time trying to make her jealous. You're sly, so you already have an advantage replace her, date her friend (I've done that, it's VERY effective in making the other one jealous, But I think I may have gone too far, because we were all living together, NOT RECOMMENDED). But seriously, it's time to do you man..... just give her a band-aid and tell her she's CUT
