<human>: So last week I was left MASSIVELY in the lurch after my bf of 3 months (I'd met and talked to him online for 2 1/2 months prior so really 5 months) dumped me really out of the blue.

Literally, up to about 40 minutes before he was due to come meet me, he was texting calling me beautiful, saying he couldn't wait to see me. The night before he was snapchatting me pictures of a hotel he was staying in for work saying "we should stay in one of these one day".

He basically said that for the last month he'd felt things weren't right, but he was just "saying the right things" to make things work. 

He said he didn't think things would go "any further" with us.

But in that month he introduced me to his mum, dad, nan and sisters. He agreed to go with me to my sister's wedding and had planned dinner with his friends for me and him! I mean there's saying the right thing and seriously putting in relationship effort.

And every time he saw me he was affectionate; cuddly, kissy, holding my hand...surely that would go if you had lost feelings for someone?

We didn't "get friendly" (PG friendly) so I know it wasn't that. I've had that happen before and it's nowhere near as gutting.

Has anyone had this happen? How do you stop feeling so duped? Have you done this before - why did you do it? Or do you have any idea why someone would do this?

Can you provide a brief overview of the text?
<bot>: someone lead me on a merry dance really making me think we had a future and dumped me out of the blue before things "got serious". why would he do that?
