I completely agree with you,Ragini is married to Anmol longer than Ranvir .She may be still in love with Ranvir and confused about what she feels about Anmol but Trust and Love are two completely different things ,you can stay with a person whom you trust even if you don't love,but you can't stay with a person who you can't trust despite how much you love him.
Ragini has been married to Anmol longer than she had even known Ranvir(arleast in Bidaailand)..so why wouldn't she trust him..
