The art exhibition

Clary has been distant lately
She is always working or "too tired" to spend time with me.
She spends all her free time at the gallery.
We haven't even had sex in two weeks and as her husband I can't help but think to myself
Is there someone else?
After seven years of marriage has she fell out of love for me and in love with someone else?
I intend to find out.

Clace fanfic, I've looked and I can't find any fanfics where clary is the 'Cheater' so yeah, this isn't me saying she is one of course
