Sorry for the long post, I am not in a good place just venting and desperate for advice and feedback.

We had long mediation and settlement talks yesterday. WAH has started saying everything is going my way, finances, custody and that I am not budging. His need to get a quick D is so strong that he does not seem to want any hurdles. Spends time and talks about love for the kids but immediately agreed to having them only for couple of days. As a mother I do not understand how you can go without seeing them for most part of the week but he is okay with minimum custody if it means a quick D thru mediation.
I made it clear I do not want to own anything jointly after this because he wanted to keep some things to be resolved post D. He was upset I was not being more lenient. Even said he was not in here to swindle me but he was getting out of the MR because I was judgemental and not emotionally available. I just validated but stayed my course.
He wants to throw birthday parties together for the children and plan vacations together to home country, I said no to both to which he was annoyed again. I mentioned any kid would love to have 2 parties and until things are figured out in future I do not intend to host anything togehter.
He does not want to pay child support but wants to manage expenses thru an App, split it halfway or contribute little more based on income, I said if he is ending this legally I would let law decide child support and that I dont want to have private convos for the rest of our lives about child care expenses.

I did speak a lot, I should 180 on that really, but at least I stayed calm, patient but persistent. I using the term single mother bothered him a few times, he started saying dont act like a victim and he has said that before to which I said neither I nor my children are victims and that we will do fine.
I am using the term I and my children, that is pissing him off, he says he is not abandoning the children and I am beign selfish as always by just prioritizing my life and theirs. Should I say our children instead? I do not use We, Us or our anymore as much as possible in convos.

He mentioned we have to see each other almost everyday due to children, even if it is not his day with kids he will be available to pick them up or drop off or anything else I need. I just mentioned that he is free to do as he pleases on his days, if I am really sick I may request his help with kids but other than that I wish to manage on my own. I also said seeing each other every day is not helathy for either of us to move on. I do not want to pretend to be one happy family post D, that is confusing and unhealthy for everyone including the kids and I made that clear to him.

He wants me to move to another state with him post D, I said I would try but I wouldnt jeopardize my career over it since I need my job as a single mother to feed and put a roof over our heads. He stated that he is clinically depressed for one year and I am torturing him more by not agreeing to anything and helping him out, I just said I am sorry he felt depressed and that we did not have a R where he could share it with me but with the way things are right now I will have to keep my job intact.

This morning he saw a handyman come in to repair something, I had not mentioned to him that I was hiring a handyman as I am paying for it on my own. He said I understand you are tyring to be independent here but since I lived here for so long I would like to chip in, I said its ok I can manage but he said he wants to contribute so I responded saying thanks and i appreciate it.

This may not be DBing, I may be at the juncture where he has been told I am ready for what is to come and I am moving forward because I have kids to raise. Should I tone down? Did the convo get too out of hand? Please advise and point out any mistakes, it was a 2 hr convo I have only recorded the stand out points I may have made other mistakes that are not mentioned here. Am I being too aggressive here? I did mention that this is not a mutually concentual D, I am cooperating with mediation only because it is what is good for the children.

Mediation talks are so close and it seems like the end of the road, am I nailing the MR coffin shut with my behavior? I want to fight for the MR, to stand up to what we had, but I am agreeing to mediation because he is offering good terms for the kids, I have checked with L. Sometimes I feel I should contest the D and pull it out but that is only going to make things bitter. I feel so lost, seems like with mediation I am giving in to WAHs craziness but I also know it is better for the kids and me instead of the legal battle.
