We've been married for more than 10 years and have 3 children. My wife however can't seem to stop seeing, chatting, or phoning her ex. Its always the same. She does it. I catch on, and she, first denies it. Then doesn't remember. Then as I lay out my proof, she admits to only what she has to and never anything more than I have proof of. I am so, very tired of being the only one full time in this marriage. What should I do ?
