Amazing bro what I can say is, you are still in love with her and ur finding hard to forget her. U look like ignoring her but everytime you ignore her, u use to think that why did I tried to ignore, did I do right, And this is what I think love is. My first suggestion would be go and give her a bday surprise telling "I love You".

Second suggestion would be if you really want to be away from that girl then stop thinking anything abt her, stop replying her messages and stop posting in sajha seeking suggestions, these things will help you remind her rather then forget. But I know u can't do that cause u still love her. Go admit your love and be together!!!
