How to convince my sister that she is a fool in love??!

[LalaLainy]

My twin sister and I aren't particularly close, but we communicate by email quite regularly and I feel obliged towards her as we have no other family. Four months ago she fell in love and moved in with this guy. Warning signs were everywhere - he is 10 years older, not even divorced from his wife yet, etc. But he is a decent guy and treats her well, so I tried to be supportive.

 

Yesterday she told me that he just bought a new BMW. She says that she is going to sell her own car (for about $10,000) and give him the money so they can share the BMW. I think this is a huge mistake - her car is her only material asset and if they ever broke up she would never get the money back. She would in fact be left homeless and without a car.

 

I have tried talking some common sense into her but to no avail - she is filled with this romantic notion of merging everything in her life into his. The relationship is volatile and I always get the brunt of any fallout between them - I am always left to pick up her pieces and help her sort herself out, and she always goes back to him. I know that if she sells her car for him, and they break up, I will be the one supporting her both financially and emotionally for the next few months.

 

I am just at my wits end - she is not listening to me. Any advice on how to handle this situation??

It's very hard to convince someone that they are making a big mistake!

 

I had a similar situation and after we dated for 3 years my family actually had an intervention where they all told me (one by one) why I should break up with my awful boyfriend. I was living with him at the time and my parents offered to let me move in with them until I was back on my feet.
