my failure

i am ravi, for past 7 years im in love with a girl and she too accepted me before 7 years. we spent time with each other and our relationship was ok till now.but as my family is a backward family i used to ask her to pls generate a bit of patience so that my family can accept her. she too understood that and answered positively to me and she said that i am disturbing her i said that we need to have a temporary gap because it is our career time.and i maintained a gap of 15-20 days meanwhile she found another guy who showed love towards her.. and the situation have become such worse that she is saying that his love is better than mine.. and asking me to break up permanently.... i am very disturbed.. i always wanted her as my girl.. the main reason of my disturbance is that i am unable to convince my self that she is going in a right way..... pls help me i want to save her and also i need to come out of it..
