imaginary motivational scenario.
so you think you are polyamorous, that is new, you are a jalous limerent. and why you think that, because "you fell in love" with a cutey. You allowed it to happen while you are supposely in love.
What you think you can obtain, a flirt with a girlfriend, a broken hearth from someone you care, and kids that will just not understand what happen and will be anxious.

Let put thing into perspective, once you understand what commitment mean, you understand what love is made of, you know you cant break the rule without hurting everyone.
You understand long time ago that you would not cheat because you cant stand being cheated.
You dont do arm to your loved one that you wouldnt do to yourself.
It is true that you can expect your way of life to fit your partner.

this story

It happened, she told me that she love someone else.
The short pause before she say something else is infinitely long. I had time to think about her cheating, me crying, me beating the unknown guy up, divorcing, the eyes of my kids once we announce it.
She told me that she still love me and dont want me to go. She want the familly to stay the way it is.
in my head(Were did I miss the boat. Are we fallen into banality. Are we too busy and the love just died?)
she said : I choose us. But I wont be able to say goodbye to him.
still in my head say nothing (what can i do to save my familly, how can i reconquer the woman of my life, how she allowed it to happen)
her : Do you still love me ?
me : I ... I do
I now lying on the bed looking the celling.
her : we can work this out.
me : date him
her : NO!
Me : limerence can wear off rapidly once you know your object
Her : sometime it lead to more romance.
Me : well change strategy
Her : just as friend
Me : I trust you, I love you.
At the end of the week they were dating, just as friend. This is the boundary we set.
And the weekend she were evidently absent.
The whole next week she was out, with him I suppose.
My mind always wander but I seam to successfully act like normal in front of her dans the kids.
But anyway, when she is here, she is somewhere else.
One night she came back at home and told me, We kissed.
Every evening she spend with him were reprimed anxiety, every work day were long and empty, but at this moment it flew out of my eyes as tears.
Me : because i love you so much, i dont want to ask you to break you own hearth for me, but i desperatly grief for it.
her : I dont want to leave you
We made love, and she was there with me for the first time since she became limerent.
The next morning, as i watched the celling the whole night, I welcomed her with breakfast in bed. Flower, I wanted to remind her that she love me.
Her : went i am with him (my throat knot) I think about you
Me : when you are with me you think about him.
I asked to stop. She didnt. I told her I miss her, she didnt spent anymore time with me. One morning she returned hone after her first sleep over.
Her : i slept with him
Me : ...
I jumped on her. i must not let her remember a wonderfull night without me. giving her a kinky orgasm would maybe bring her back. she let me do it bit didnt enjoyed a bit of it. so i stoped.
Me : we will divorce
her : ...
Me : do you remember the kids ? you are supposed to love them more than I ... and him
her : you are only making me hate myself

her : i still love you
me : you are only ashame to face de reality
her : you are first in my life
me : but i have to wait for my turn and feel him through you.
