How to get her back

Hi everyone. My ex broke with me 5 months earlier in a two year long relationship and I applied no contact rule after 2 months of breakup. Meanwhile she was in a rebound relationship. After 10 days of No contact she came running back to me saying that I am the perfect one for her. We were happy for past two months and now again she wants to move on. The reason shown by her is her family(saying they wont accept me). She says she has feelings for me. I don’t know if No contact rule works in this situation. Suggest me.

What is the problem with family ? Is it because of different religions ? and why they don’t accept you ? How was your relationship when she came back and it was her decision to come back ?
