I don't think Gauri loves Omkaara but yeah she likes him and adhore him as a saint which i don't like really. She is not going through any of his POV or any of his flaws, What exactly he wants, how he feels. Though she knows some of his side by being Chulbul in previous but she is not reminding any of those facts. Even when she was chulbul she hasn't get through any of his flaws or pains clearly as I wished. She simply gives her statement in his pob without acknowledging the full problem.
Love is a very heavy word atleast for me. Without completely knowing a person u say U r in love and then after knowing all his bad sides u left him these kind of facts I don't like from a lover. If Gauri really loved Om then she would felt all those pain what Om is going through. We Om fans can feel the pain but she can't get through his POV. So I don't think she is in love. Yeah she worship him but her worshipping is also not the real worshipping.She also like him. But liking and loving is a complete different thing.
