Ultimately, it's still her choice to get married. It sounds like she's not making wise choices, from your point of view, and I know that's frustrating. But there's nothing you can safely or reasonably do. Trying to force her into the choice you want will make her mental health problems worse, erode her confidence, and may drive her further away from you.


You clearly care about her a lot, and want to see her happy. I'm sorry that you are watching her suffer so badly recently, with her PTSD and suicide attempt. But the best thing you can do it respect her right to choose. If she makes the wrong choice? She's an adult, and she can handle the consequences. Sometimes people have to make their own mistakes.


But unless she's abusing someone else, there's nothing that would make it okay to ignore or disrespect her wishes. You are allowed to be worried about her, and it's okay if you would make different choices. You can still love and support her through this. Wait and see what happens.
