My wife's affair

Nick
Ladies thank you for your helpful advise however to be completely honest my wife and I are struggling with our relationship and our marriage. You see for the past 5-6months my wife has been having an affair with another woman. To say the least I'm absolutely devastated. I personally caught the them together and she assured me many times that it was over, only to find out she has continually lied and continued seeing her. She finally convinced me it was over and we agreed to go ahead with the IVF as planned before the affair happened,  which the IVF was successful. She is 8 weeks 3days. Lately she has been putting some distance between us. And today I caught her out on another lie regarding this woman. We had another argument and she finally told me that she is struggling with her sexuality within herself. I am so lost as a husband and it's tearing me apart cause we have two beautiful children together. Girl 6yrs and Boy 3yrs. I'm still in love with my wife and even tho says she still loves me, her body language and attitude towards me says otherwise. This my second marriage and it's turned out just like my first, just no kids in the first Marriage. I feel like I'm a failure to myself, my wife and my kids. Even after I knowing everything she has done, I still want to work on our marriage and try to fix this nightmare. I tried packing my bags and leave tonigh but my daughter sensed something wasn't right and cried for me to stay, to which I did. She is laying next to me right now asleep. I am so unhappy and don't know what to do. It's like I'm in limbo waiting for her to make up her mind weather she wants to stay with me or be with other women. I gave her my wedding ring back coz I made up my mind to move out but that didn't happen. I can't even watch girl on girl anymore without picturing my wife and the other woman. It's really messing with my head and then some. I've lost 13kgs in weight due to all the stress, anxiety and depression I've slipped into. When I first met her she helped me out of a dark place I was in and now she's put right back into it. I've turned into a person I really hate being. Maybe I'm just destand to be alone for the rest of my life? Maybe this is my karma for the bad I had done in the past? I am to get help but it's all taking soo long to see someone. Truth is I'm still in love with my wife and work it out and I don't want leave and hurt my kids but I'm not sure just how much more I can take.
