Sorry to tell it like it is, but you two will be together in some place... not a nice place. Suicide is an insult to God, especially for this ridiculous reason.
They don’t sound like Christians.
I shouldn’t even read posts about this topic because they usually end up ticking me off. She had experienced suicide attempts at age 15. She obviously had mental illness. So she was ill. So I think Christ would have as much compassion for her as he has for a 15 year old with physical illness. Because he created each of us, and he loves us imperfections and all. And after my mentally ill father completed suicide I had a dream as clear as day where Christ wrapped his arms around him and told him he would now be at peace.
My self-righteous grandma (his mother who stood by and watched while as a child his dad beat the crap out of him) told me he was burning in hell for giving up. I never spoke to her again. Ignorance. Please don’t pass it on.
Their God has the upgrade package that celebrates suicide.
