WW having affair and pushing for divorce

[DB346]

Both of us already have lawyers...she retained hers within a week of leaving. I already have all the proof needed to prove adultery. I'm just not willing to give up my son and feel like she has forced me to not really have any other option but to file. She hasn't had OM around our son at all, but she leaves him with her parents most of the time on 'her days' to spend her time with OM. I've definitely asserted myself to spend more time with my son since confirming the affair. My ONLY priority right now is to do what's best for my son and fight for as much custody as I can get.

Saying all of that, I have definitely reached the point that I have accepted the end of my marriage. I don't think there is any scenario that doesn't end in D. Even if she did a complete 180 and wanted to R right now, I don't think I would be willing to take her back. I would still want, at the very least, the separation agreement with 50/50 custody and I wouldn't be willing to have her move back to the house. I'm not even sure I would want to date her, let alone resume our MR right now. I've spent every minute of free time, and then some since she left working on myself, while she has done nothing but lie, cheat and manipulate. I would need to see her make more of an effort than I think she is capable of doing to convince me. But, none of that matters because she is still actively involved with OM and we are almost completely NC.

I tried to have a conversation with her about custody before my last conversation with the lawyer, but she jumped in to gaslighting and blame-shifting, which came as no surprise. So, I'm done trying to discuss it with her. My lawyer is VERY pro-dad, and is also very familiar with WW's lawyer, so I trust her advice on this, even if it wasn't what I really wanted to do. I know that WW is betting that I won't pull the trigger because she still doesn't believe that I have let her go. I honestly believe that she thinks I'm still hoping that she will come back and that I won't push, but this was HER decision and I am not going to protect her from the fallout.

I'm definitely still hurting over the situation, but I have definitely 'dropped the rope'. I feel no attachment to her anymore. I'm comfortable with filing for divorce, I'm just uneasy and nervous about still ending up with minimal time with my son. She has no respect for me, and no concern for the pain she is causing me or our son, so I am not worried about her reaction to me filing for adultery.
