Interfaith marriage

My close relative is marrying her date ( well pursuing as a friend) of 2.5 years from Kashmir , we are kayastha - bhumihar bongs from traditional liberal families . Her lives in Posh urban Kolkata , while we come from outside the state

I heard the man lied about being a kashmiri pandit to the family of my r. and due to same arrangements, engagement took place suddenly after our own cousin 's wedding within a year. (14 months)

She left her high paying job at public sector to be with him and shifting to IT .. in Banglore with him .

Families are letting custom marriages for respective relatives , real marriage will be under SMA in court .

My mother want to cut ties with her sister due to this , she said to me openly .

I am attending the wedding on the bride 🕉️ side .

Should I opt out or experience as a Political right person , I do respect and hold admiration my cousin deeply for her scholarly endeavours.

Was leaving a good job , marrying into a conversative household good for a outgoing liberal woman from Bengal a wise choice , which may come to haunt later in life .. I know it's decision of the person to make but any views how one should see this .
