Affair with colleague

So I fell pregnant. My colleague knew all about it and he promised to not confront my husband about it. My hubby on the other hand was thrilled at the prospect of being a father. I told him I was not in the mood for sex and would only have it with him occasinaly. but obviously I was sex hungry and therefore have sex with colleague behind his back regularly. My Sister lives a bit far away. she knows about the situation. I told my hubby that sister needed some help as she had just moved and I would stay with her for 3 weeks. Me and my colleagues jobs allowed for temporary transfers to other cities. So instead we both went and stayed at sisters home. We fucked like newlyweds through out the 3 weeks. then later we moved back. I continued to see colleague regularly and every time hubby asked for sex I would just like and tell him I wants up for it but truth was I was becoming less attracted to hubby and becoming more drawn to colleague…. more to come
