I like this guy... and he likes her...?

so i used to really like my best friend's ex, (she was ok with that btw) and he was finally available so my best friend said to go for it but i was too shy and then so i had another friend who was close with him so i told her to talk to him for me and she did. a lot of minor things happened over the next few months (he called me pretty, said i was nice, said hi occasionally) ALL to my friend (the one close with him, not his ex) anyway, so she never told me any of this stuff because she was jealous. BUT, she decides to tell him everything i would say to her about him (he's so HOT, i love him, blah blah blah very embarring stuff) and he started to look at me differently. so thats the least of my troubles. now, they're going out. i'm like are you kidding me?! so i had a fight with her and held a grudge for a LONG TIME. and she still doesnt like me. and the guy never talks to me anymore. and they PDA only when im around. HELP ME. what should i do? ignore it? or say something?
