I've been talking with a 'friend of a friend' online so although we haven't met yet i was fairly sure he'd be ok and not an axe murderer 
We arranged a date for next weekend.
The problem is he suddenly upped his ante and taken to messaging me non stop from morning until night every day of the week, even whilst he's at work. If i don't reply in a timely manner it begins again, starting with "are you ok?". He messages me so often i've now lost all interest in him and its put me right off.
He asks what i'm eating, what i'm doing all day, what i'm watching on TV. He's sending long sloppy messages pouring his heart out telling me what a gentle and genuine guy he is, how he will treat me right, how his ex was a gold digger who left him for another man but he can tell i'm nothing like her. He apparently can't stop thinking about me and feels as though he can tell me anything. We have never seen each other in person and only chatted on a superficial level, never anything deep (at least not from me). He spends a lot of time trying to convince me of how genuine and sweet he is.
Now i've resided myself to the fact we aren't compatible as i can't deal with clingy people, but aibu to think these were potential red flags? After being in a long relationship with a raging narcissist i'm extremely suspicious of anybody who comes on this strong so soon
