Let's have a answer from my experience .I was having a girl friend and she always helpful in my work and so we share our cellphones ,laptop and many more thing with each other. From my family my parents knowing about my girlfriend but her parents were not knowing that we love each other.

When we were around 20 years we had opened a joint account in bank in which we had saved our money for future. My girlfriend comes to my house but I was not going in his house. After few months my girlfriend mother arrange a marriage and my girlfriend was not knowing and marriage was organised and so she has to listen her parents and so she marriage .

But what happen to my bank account you have question. In this situation my girlfriend call me and tells me everything about it and gives me the whole money which we have in a joint account. But I refuse to take money because I was angry on her and tells her to leave me alone.

So I request don't open the account until you are marriage .
