So,...h left me after loads of comings and going after I’d discovered his affair. He then found out I was dating and lo and behold wanted me back. I tried to want him back but couldn’t get over the way he’d betrayed me.I had been casually dating, but am now serious with someone. Ex is being an absolute cunt to me and I’m fed up. It was all his choice to leave me. I wanted to take him back for kids and family. But I couldn’t feel the same. Im exhausted with it all. What to do?
