I won't protect you...

Things aren’t fabulous here lately. Haven’t been for a long time.
I have huge problems if my sexual needs aren’t met, and my pet appears to have no desire to fulfil these needs at the moment.
Everything has returned to a dreary vanilla… only worse.
Sex is now the traditional “jump on top, fuck for less than a minute, feel terrible, jump off and sulk”.
Foreplay has vanished. If I even attempt to regain some sort of intimacy I am groped in return.
Anyway, by the by…
Yesterday we had an argument. I tried my hardest to turn things around and was promptly taken for granted.
I attempted to initiate some form of sex in the morning, but pet was too tired. Once I began to think about it, I was actually relieved. I can no longer deal with this “woe is me, I’m crap in bed business”
Today things went from bad to worse, with an ensuing thrashing about of the beloved Facebook.
My pet has mainly female friends… slim, pretty, female friends. I am wary and jealous. My husband stopped having sex with me because I am “fat and unattractive” and then went off to fuck a slim, young, pretty Russian. Of course I’m scared. I’m 12 years older than him, I’ve had baby # 4 in the last year, I’ve gained 2 or 3 stone and I hate myself.
I do not feel any inch the Goddess or Mistress, and with this attitude I’m sure you agree… I do not deserve such a title.
What struck me most about the whole argument is that he said “I won’t protect you” and continued (I can’t remember the exact words) to explain that he would not consider my feelings and my irrational jealousy and would not go out of his way to prevent me from being hurt.
I have yet to sort out exactly how I feel about this. I go from despairing (I need to be looked after) to angry (well fuck you, I’ll go party my ass off and see if I can hook myself a younger, slimmer, more virile stud).
Despite the fact that he has just turned up with a Starbucks (didn’t speak, just put it down next to me) in an attempt to reconcile, I think he has probably just said the worst thing I’ve ever heard.
Maybe I’m over-reacting. But I feel seriously hurt.
I need to think…
