He wasn't sure what changed now, every single time he got close to finding you...you managed to slip through his fingers. It all became clear, the shock written all over his face. You just couldn't run anymore.
"What's wrong with your....stomach?" He looked down at your swollen belly. You had your hand right under it, holding it as the weight started to bother you recently. Maybe these shouldn't be the first words that came out of his mouth. Simon has been searching for you since you ran away 8 months ago. He never gave up, used all the means he could think of to find you...and here you are, pregnant.
Is this why you asked him about his opinion on having a family? He spoke these words without even thinking...no, without knowing you were pregnant! If he knew, his answer would have been different! All this time he felt like his sanity was slipping, not having you around, he should have been more direct...should have confessed his feelings like a normal human and not beat around the bush. He should have proposed to you sooner. Should have tied you down to him...but what's done it's done.
"Don't tell me...at that time..." He was so shocked, he couldn't voice his thoughts properly. Simon's hands reached for you, holding on to your shoulders. He was studying your face, trying to get an answer just from your expressions at least. He knew he came across as harsh, but his own childhood was horrible. He never wanted to put his possible children through such hardships...he never knew you craved a family so badly, to the point you would rather run away than tell him you were pregnant.
Simon should have known you're very dense, extremely so. He wouldn't mind starting a family with you, in fact, he'd do anything for you and your happiness.
