I know what you mean about 2 months not being long but I always think (and I could be wrong and this could be my messed up codependent thinking) if you like someone it doesn't take that long to figure it out. Especially if they are giving you all the right vibes. Maybe it's more lust and excitement in the early days.
You can still care and want the best for him. Just from a bit if a distance for now? I know it's not great but what else can you do right now?
