This is her pattern I truly believe she is untreated bipolar I don't even know if he knows that about her.
A few weeks or a month from or so from now when she's in the next phase I think this will be bad.
My advice still stands. If you want to in any way be helpful to your sister, your job is to try to strengthen the bond between you. Criticizing this relationship can't possibly have a good outcome.
If your sister is hesitating to accept his proposal, she at least has the ability to stop and contemplate before making an impulsive choice.
If she truly has bipolar disorder that is undiagnosed and untreated, there are far worse things she could do while manic than marrying some dude she met 6 months ago, especially if the man is kind and cares for her. He may not know that her mood may change, but that's a risk he takes by proposing to someone that he doesn't know all that well. It's not your place to warn him. He could well be a nurturing, stabilizing influence in her life.
I say this as someone who knows bipolar disorder. My brother died from it 5 years ago. You can't cure your sister and you may not be able to protect her from the symptoms of her disease and the damage it causes in her life. What you can control is how you treat her and how you love her. If I could do it all again, I would focus more on loving him and enjoying him and knowing him better, not pathologizing him. I miss him terribly.
