<human>: Hi guys,

I'm having a relationship with this girl for several months now. We are in love and everything is wonderful.

The problem is that she is still technically involved in a relationship with her ex. They're having problems for something like 8 months now, and now that she found me she wants to stay with me.

At the same time, the relationship with her ex lasted 12 years. He told her that if she's going to leave him for another guy that's fine for him, but in that case he will cut all the contacts with her.

She said that, even if she doesn't love him anymore, she can't simply lose him after 12 years. She would like to have him in her life, even as a friend.

Now she doesn't know what to do and she told me that she may get back with her ex just to keep him in her life, even if that means living a relationship without love. She says that he's like a brother for her.

What I'm thinking is: if she really loves me, shouldn't I be the first person in her life? I get it, they've been together for 12 years, but if now she's really in love with me, the desire to be with me should be stronger than everything.

And even if the ex would be okay to stay in touch with her, should I be okay with that? I really don't know.

What should I do? What should I tell her? I really don't know why you should want to stay in a realtionship without love just to keep a person in your life at all costs.

Could you distill the essence of the text into 1-3 sentences?
