Am i splitting?

I'm currently being close with this one person, he's been treating me with so many kindness, we match very well, and he feels like "the one" for me after getting to know him for months, until one day i discovered something that gives me ick because i feel like this thing is very horrible in my point of view. now i just could not see him the same way i seen him before, and the problem is thing is actually not verified to be true, but im afraid if that's a fact, i don't know if i can handle it. i feel worse because of this and i hate it so much. i asked him if we can talk abt this, but i need to wait until we can meet face to face which is next week. now im not sure on what to do to stop overthink about this
