WW having affair and pushing for divorce

[DB346]

Been a hard couple of days for me. Not because I miss WW, but because she is being very difficult about custody of our son. I want 50/50, but she only wants to agree to give me every other weekend and a couple evening visits during the week. She is so angry and hateful toward me, yet she tries to project those feelings to me. Accused me of wanting equal time with my son only because of my anger and resentment toward her and that my hatred of her is preventing me from doing what's best for our son. I don't have anger or resentment toward her, and I definitely don't hate her. She hurt me, but I know that I can't control her or make her be the person I thought she was. I just want to move on with my life but she's using our son to try to maintain control over me. This is just causing me so much stress. Unfortunately, it looks like I am likely going to end up needing to file for an at-fault divorce because I don't think we are going to come to a separation agreement and I'm not willing to let this continue this way indefinitely. I have no protection right now and that is not a good feeling.
