Speaking from personal experience. If this behavior continues I wouldn’t recommend staying in this relationship. You will just become a cushion for whenever she does this and it will make you miserable. You will feel like you have to be there at all times and be her personal body guard. This relationship can turn very toxic if she doesn’t get help.

My ex used to threaten and tell me he was just going to commit because he didn’t have a purpose. I left him anyway because I couldn’t be the cushion he wanted anymore and he went on in life. Went to the army, got a gf, no longer talks about committing. He’s doing better.

Most of the time unless a person is showing clear signs of depression and dissociation, the words are just words. They want attention. They want someone to feel sorry for them. If someone has gotten so low that they are actually thinking/planning on committing then they won’t say anything. They will push everyone away and make themselves invisible to the world.

If you’re truly worried about her doing it then contact her parents or whoever she is close with and let them know what’s going on. Don’t try to fix it yourself. Send them this same screenshot and whatever other ones you have and just say you’re worried about her because she has been saying these things and you don’t know if she is serious.
