Affairs..

So before my husband and I got married, we actually broke up because of his cheating. he was paying for sex and I didnt find out until a week after the wedding. I've felt distant and not so in love but I'm big on keeping faith it can be fixed. but I'm to the point where I dont know. I started sleeping with one of my coworkers... out of spite towards my husband. the problem is I'm attracted to my coworker and he wants to be with me. he kinda has a problem sleeping with a married woman but we make each other happy and idk what to Dom my husband has no idea
