"I don't want to break up the marriage".
Girl...You are not the one playing around.
Your sweet children, 1 and 3, of course deserve the Best Daddy in the world. Their very own Daddy would be the best, if he were the best. :(
All of us females can thank our theocratic brothers for informing us that ALL guys wank. I did not know that. Wanking = OK. Emailing/flirting with females while married = NOT OK.
I will be thinking of you. (Holding hand over internet) It is so unfair. Most normal guys would love to have a young wife and family, whether of the same religious persuasion, or not.
Try to be a pillar when around your chilldren. Be strong young (former) sister. You are not alone. We are here for you.
