I dated a girl for 7 years and we wanted to get married. However due to parental pressures we had to break up and she got engaged to some other guy. Since then i decided not to talk to her and even she didn't try contacting me. Last year, i cleared my CA Finals and she congratulated me through FB though we are not friends on any portal what so ever. Now its her birthday today and the problem is I am constantly thinking of messaging her. The problem is i still have not been able to move on and miss her like crazy and though wishing her would be entirely formal but i am scared if she replies or asks me anything i might break down or act weird. However it is also necessary for me to get a closure on her so that i can concentrate on other relationships as well. I am not able to decide whether should i wish her or not?
