Apologies for long story but need to give context.
Ex dh has messaged tonight to make a couple of changes to contact over the next 4 days. He wants to replace a morning of contact with an after work trip to the park on a different day. The kids aren't available on the evening of the day he has suggested and I've told him this.
I didn't go into detail of why they aren't available (and don't feel I should have to) but he's demanding to know "what activities are they doing that means I can't see my children on 48 hours notice".
He is also stating that he doesn't have to pay me child support until after the divorce......because I earn more than him and I've "made him homeless".
backstory/context:
Separated almost 4 months now- 3 kids (16, 8 and 6)
He's living with his parents
I'm in the family home and paying all the bills myself
He refuses to commit to a pattern of contact "because of his shifts" even though he has a 3 week repeating pattern of shifts
He does do overtime to supplement his income
Hasn't had the kids for any overnights since we separated
In terms of weekends off, he has 1 full weekend off in 3 and 1 half weekend in 3 (Sundays) - never does overtime on the weekends, only on weekdays.
Since separating he has spent time with his children on only 1 of his full weekends off (so 1 of a possible 6). He spent the other 5 "unavailable" pursuing a new relationship with someone else. (No problem with the someone else, she wasn't an OW, he just had her lined up in the wings ready to go)
When he has informed me that he will be "unavailable" to his kids. I just accept that and don't ask for further detail.
I do have an appt with a solicitor but it's not until a couple of weeks from now.
So it's ok for him to be "unavailable" but not the kids to be "unavailable"?
I'm genuinely not withholding the kids for no reason. There's only been a handful of occasions since we split where I've had to say "no sorry the kids can't make that day/time" even though I'd love to do it more often because I really don't want to have to see him myself.
