GREETINGS

I am engaged in an arranged marriage.He earns a very fat salary,seems humble and nice,is hard working and good but looks at girls a lot and he never tells me that he likes me,never talks sweetly to me,always puts his work and friends before me.Its been six months and i still feel he doesnt truly like me and neither do i really like him.And in the meantime,my previous colleague whom i met at my first job and got close and shared everything with him including that i have depression and stuff like that, came back and told me that he really loves me and wants me back now and he doesnt want me to get married.He says all sweet things and shows his love and care for me unlike my fiance.I am falling for this because i feel love and care is more important than money and status in society .I dont know if i am right.But i am in a very sad position,my marriage is in the coming month(december)and all the preparation has been done and my family and relatives will kill me if i tell them i dont want this marriage .My previous colleague seems really depressed about my marriage.but he is of an unstable mind and brought up in a broken family.He is a punjabi and i and my fiance are malayalis.I really dont know what to do but i really dont want to be in a loveless marriage either.What do i do?please advice me
