Relationship Issue

We r in relasnshp since 2 years. Initially Evrythng WS fine. Bt one day c said that although c loves me, she cant marry bcoz of family issues. I tried to cinvince her many a times but she doesn't wants to embarass her parents. We decyded to move apart bt only in few days we realised that we cant live without each other for a singl day. She came up with a solusn that we will cntnu to love each other till we get settld and then marry as per our family's wish. I love her a lot. So does she. But I m confused. Is this the correct solusn. She is junior to me and for higher studies I had to move to another city last year and nw she is about to finish her college. Recently she went out frequently with his best friend (his best friend is with her even before me), it was little wen she retured back and I just frowned upon her but she said to have faith on her. How can I allow my girl to b wid some else so late at night but she doesn't understands. Its hard to move away from her currently. Plz help
