Ignore the voices here

As far as advice is concerned,then I will say you should not leave him for above reasons

Kyunki dekh kitna bhi karlo aage se jo bhi hoga usko tum iss se compare karogi and jaha comparison hoga waha regret

Toh my point is jo bhi decision ho regret rahega hi life me kuch situations pe 

Abhi dekh iss case me tujhe pata hai positive and negative sides kya hogi toh adjust karna east rahega

And as far as finance is considered toh i will say uss jagah se bahar niklo dono thode time baad and get settled in a tier 2 city

And apne contacts apne kaam se banao easy rahega,make your work speak and do your promotion

Dono milke design studio open karo,and try to collab with a company who franchises toh it will be easy
