Me and my wife of 9 years we are getting separated. Just a small back story, she started this new job last year and since then her attitude has changed a lot. It’s pretty clear that she is cheating and I have ask her on her face if she has found anyone. She keeps denying . I am at the stage where I do not really care about our relationship. I do not want this marriage to work, as she has crossed all the line. And We have a 4 year old daughter. Before our daughter was born we use to have different arguments. But since the birth of our child the arguments/fights is/was about our daughter. She does not pay any attention to our daughter. When the whole issue started, she wanted me to give her divorce and she wanted me to keep the house and our daughter. I was really fighting for our marriage and didn’t want that. But then she started staying out, won’t come home. Initially she would tell me her whereabouts and slowly I gave up on her. She would not call once in a day to check on our daughter. Just for the numbers, she stayed 18 nights outside between April -December 2023. For the record, I do day care pick up and drop off, bath, meal prep and feeding my daughter, taking out to park, playing at home. My wife once in a while feeds her. She does not spends any time with her. I offered my wife that she can keep the house and I will walk out tomorrow with my daughter. She does not want that. She wants 50-50 custody. All I care is well being of my daughter. I spoke to her many times that why is she not spending any time and keeps neglecting our child. She has no answer to it. Any advice would help. Now I just want out, the question is can I ask for full custody of my daughter.
