<human>: So I'm now regular here..which in itself should have been a warning sign from the outset. I've had to delete my posts because he was trawling through my FB and Reddit posts on his iPad and he knew what I had been saying. 

We had an argument about his ill-treatment and verbal abuse of his aspergers child. Then he proceeded to wipe the floor with me and remove all sign of me from his life. Because I criticised him and said I didn't agree. He has written me another long-winded and brilliantly manipulative email about how he is heartbroken and devastated to say goodbye to me...but simply cannot allow himself to be hurt again by someone who questions his parenting. (I myself have 3 children and I'm not afraid of being told where I could improve-within reason)

The whole email was based around how it was me who made all the mistakes..me who pushed him over the edge and ruined our "perfect" relationship. In fact I am so numbed by that email I am happy to PM it to anyone who could help me decipher it...I'm totally stunned and heartbroken by his reaction. He finished the letter by including some special memories that we shared..and a kiss. But has since stonewalled me and blocked me on FB, email and phone. 

I also know that he was back on the dating site within a week of breaking up with me. The guy who wanted to marry me and spend the rest of his life with me! A week! I'm so upset and devastated by this change in him..I don't know how to move on. I feel paralysed by grief almost...even though I know his treatment of me is cruel and unfair. I just can't seem to get my head around why he has done this. 

I need advice..or a kind word, or a kick in the arse. I need anyone to help me move on from this horrible, painful place. Because I can't handle feeling so bad about someone I loved so much.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Boyfriend dumped me for criticising him, has now wiped me from his life and is back on a dating site all within 1 week.
