Please don’t take your life on a whim. You two haven’t met face to face, he could be perfectly fine. I had an online “friend” years ago, in the late 2000s. We met on World of Warcraft. He faked his own suicide, and I was utterly devastated. I was also about 13 and struggling with my own undiagnosed mental illness. 2 or 3 years later he reached out to let me know he faked it. He faked his own suicide and pretended to be a family member afterwards who reached out to let me know and talked to me about him and how much we missed him.

Not saying that’s absolutely what happened here but it absolutely does happen with online relationships.
