Dumped for having an orgasm?!

"Dear Housewife,

I have just been dumped so suddenly by a guy who I thought everything was going well with. In fact he seemed more keen to see me all the time and we spent a lovely weekend just past in the country.
He said it was because there was no spark and that it wasnt quite there - which I am reading means : I was bad in bed. I thought our sex was good and getting better every time?! And I had no problem coming to a climax, although the last time we had sex he suddenly stopped because he didnt want to climax yet and asked me if I had already come - to which I replied yes because I had - his response to me was "well f**k you then", and with his tone I couldnt work out if he was joking or not.
I thought he would be happy that I did, clearly not!
The next day he dumped me, and I am very confused and very hurt. I'll get over it of course, but my confidence has taken a massive hit because it is not the first time I have been dumped out of the blue.
Just so you know, I am not a corpse in bed and I really do enjoy sex.
So confused, I'd be grateful for any answer you have.
Thank you."
