Great to read that you are chillin' at home @Faith-and-Hope. You need that.
It is all really raw right now, and as horrible as that is to endure, it puts you strides ahead of a lot of people in similar situations to you, that aren't able to change the gears from denial or fear of being alone and fear of change, into action. You acted pretty swiftly and to me that says you knew in your heart it was over & you wouldn't stand for it, and also that maybe after all these years you are now a very different person to the person he is.
I hope that you are able to enjoy the trip with the kids. Maybe it will be nice to have them all to yourself for a little while and you'll get more of a chance to have better conversations without the stress and strain of your ex being close by or in constant contact with someone in the family.
I am sorry about the kids studies, that must feel so unfair and anger you. It's no indication of their ability, you only have to be out in the work force a couple of years to meet brilliant minds that for whatever reason never make it to University. The way assessments are designed, especially when it comes to considering the neuro-diverse, they can really scare a lot of talented, versatile thinkers away. As for retaining students with mental illness and a history of interpersonal trauma.....they often don't.
Privilege is really only considered to be financial, and you do not flag on the system if you are not a recipient of government support, your struggles don't really exist a far as bureaucrats are concerned. There's still a lot of discrimination in tertiary education against people with disabilities, they do not even offer grad programs part-time or online and you often have to move to Canberra. A person with a disability moving away from all their support and medical team is quite laughable. The problem with disability advocacy is that they lump us all in together, when our needs, triggers & barriers to employment and completing education can be very different.
I think all of you guys need to get away.
I hope that your morning coffee is toasting and smelling divine!
