Someone like AK background wouldn't. And there are multiple reasons. Most importantly because in real life no one will stay with a stranger man rather than her friend or family and like I said earlier grief k wajah se pareshani me Ghar chhod bhi Diya toh ek do weeks me they come back or at least will ask someone from the family to help and not be a burden to a stranger that too during a complicated pregnancy. Her decisions don't make sense.
In the Pakistani drama also Meerab came back after 2 years and she didn't marry the guy who helped her rather made him her brother. Which is still logical.
