Should I intervene and help my friend who lost around 4 lakhs due to a Girl.

As the title suggests, my friend(22M) who has a really good tech job with a salary that makes everyone jealous (he graduated from top5 colleges in India).

In January this year while he was travelling to Mumbai on a flight he met with an employee(19F) on the flight who was not on duty that day. they started talking and exchanged socials. It was all going to fast and they started dating so fast (7-10 days). And the honeymoon phase was so good he was blushing and feeling like he was on top of the world. He never told us much information about their conversations and how serious were they. So we didn’t talk much about her and the time just passed.

3 months after their first date. I met my friend and he was all tensed and nervous that day, I foundout later that he was looking for some type of physical relationship with some other girl (despite buying her some expensive gifts she obviously scammed him and didn’t want anything to do). I confronted him regarding this and why is he all weird about his relationship. So he told me that her father was not well and she isn’t giving him time or attention due to these things. He is not sure if she is honest or she is lying. So I asked him what all did you do and did you send any money. He told me that he sent some money whenever she asked like small expenses 3k 5k 10k. Me and my friends added up all the gpay transactions and the total came out to 2.5L and the highest single payment was 20k for her father. He didn’t have any medical reports or any other proofs regarding her father illness. We all had our doubts and I went through his chats and they were so bad like he sends 20 messages per 1 reply from her (where she begs for money). He puts so much efforts but all she cares about is probably money and she is driving him crazy. She is always giving some lame excuses about how her phone was not working or “how it accidentally blocked him”. Me and my other friends told him to confront her regarding the money and he did. Her response in summary was that she isn’t lying and she is sorry that she didn’t give him enough attention or respect. But she isn’t providing any proofs which is concering. She is sorry and wants to try again. (but lets be real she just wants money.)

They met thrice in total over 4 months, after which she told him that she is shifting to Mumbai and is no longer in hyderabad but the transactions were still happening. My friend’s work allows him to work remote so he is planning to go to mumbai and stay near her. I am pretty sure she is not into him and is using for money but he can’t see through it. I am honestly kinda worried because its not just about money (he can make it back quick) but the trauma afterwards might scar him forever. What can I do to convince him and make him see the reality. (I can make a separate post about all the redflags about her).
