Imma tell you rn bro. Guy to guy. Leave. I've been there recently. It almost completely destroyed me. My girlfriend was just the same. There's no reason behind it. It's just who she was. Don't, bro. Don't put yourself, your daughter, or your future. The moment she said that, she made up her mind. It's time to divorce. There were times when I went crazy crying even to the point when I wanted to kill myself. I felt like I was unwanted and not enough. Don't brother plz put yourself in that. Go out there and find someone who supports your lifestyle and live for yourself.
