re: My girlfriend tried to kill herself

It's a long hard road and may never get better with her. I'm glad she made it. I agree with the sentiment that you have to think long and hard about yourself here too though.

How early in the relationship did you have to previously talk her out of it? Does it manifest in other negative ways for you guys? And some tough questions like is there blurriness between actual love, vs wanting to save someone.

Make sure this is likewise a good place for you to be in and properly reflecting on your own wellness.

Edit: just saw the update. Instability from her is no surprise. Again, I'll echo do you want her or are you scared of feeling guilt about not saving her?

Take this as a chance to get away, get some space and reflect on yourself. What's inspires you to call a suicidal, cheater, that places you behind another man the love of your life? It sounds like you are romanticizing a bad situation to help justify staying. Do you quietly enjoy the drama? Do you have a savior complex? What are you learning about yourself?
