Kyle was never going to be hers nor she his (not for lack of trying)
It's pretty obvious she isn't his 1st extra marital given Annies eyeroll, 'it's complicated' comment in the Cheshire housewife programme.
I'm going to sound like a right bitch but here goes.....
She's a career tramp. People randomly hook up, play away, 1 night stands, friends with benefits etc it all goes on.
People use protection, some don't need it, sometimes protection fails, some just forget others just take blind chance it won't happen to them.
There are mistakes, unwanted pregnancies & at that point each party makes a choice.
I'd hazard a guess that K suggested a termination & L refused therefore it's her choice to raise the child alone with K rightly so contributing financially.
How the hell a 2nd pregnancy materialised is beyond belief...... as in why K didn't wrap up 5 times because whatever either of them did beforehand failed miserably.
Yet a 2nd pregnancy occurs.
By this point L is fully aware K wants nothing to do with either of them.
I'd bet my house that K begged for a termination yet again L wants to continue with the pregnancy. Why put a 2nd child through the same?
She has to realise that she has CHOSEN to go it alone.
Both are equally responsible to protect themselves against pregnancy & infections but ultimately once the pregnancy is caught L held all the cards.
She knew precisely what she was doing. She's played him, played him real good. Fool me once shame on you, fool me twice shame on me.... & I pity the fool!
