I bought 100 bitcoins about a decade ago (I still have all of them). I told my GF to put her paycheck into bitcoin too and she ended up with 50 BTC. I told them that I would hold them for her. Two years she broke up with me because she "fell out of love". Recently I got a mysterious phone call from her, that she had a strange tone of voice. She was reminiscing about the past and then managed to bring up the Bitcoins. I immediately knew that she was recording me to use as evidence, so I end the conversation shortly after.
About a week later, her sister messages me and is a lot more confrontational, saying how I held those 50 bitcoins for her that they were her sister's money. Long story short, indeed it's true that she wants to sue me for those 50 BTC.
There is no paper trail of it and no admission of guilt anywhere, which is why she called me to try and extract a confession. She gave me cash to buy it back then so there is no paper trail.
Should I fight her on this or should I just give her her bitcoins? Keep in mind that when she dumped me, I fell into a deep pit of depression for years, she ghosted me and never checked up on me to see how I'm doing. I was just total trash to her.
I only escaped from the depression BTC pumped over 10 grand. I now have a new GF who is telling me to not give her a penny, that she wasn't there for me, that she doesn't love me like she does, and she dumped me when I was at my lowest, that she would never even think of doing that. Basically exactly what a good girlfriend would actually behave like.
Now she wants those 50 bitcoins, I am in a difficult position. I can't just make her rich, especially a girl that ice cold, although it is tempting to cash out a single coin and go on a lavish vacation, and post pictures of it on instagram to make her seethe.
