I think I have a situation that could use some of your blended-family experience.
My XH is moving in with his new fiancee' (they've been dating a few years, recently got engaged). He has been living in the house next door but will now be 20 miles away (on the other side of Downtown LosAngeles, so minimum of about an hour driving time). My kids homeschool part time (they are in class 2 days per week) and he doesn't want to cut his visiting time with them (I think it's so he doesn't have to pay more in child support). He has suggested that they spend an entire weekday up there instead of the 2 weekly overnights he currently has. The thing is, he works full time so he wants the boys to spend that day with his fiancee' homeschooling them. This will only be for about 10 months, since my oldest will be in full-time high school next year.
Another complication is that I am having problems with homeschooling the younger one and want to put him into full-time school but XH is saying that they (he & the fiancee' ) want to help with the homeschooling, too. So, I am expected to send my kids away for a day to not be with their dad but to be schooled by his fiancee', someone I have only met once and have no desire to co-parent with. I'm happy for them and she is welcome to be a special person to my kids but I don't want to parent with her.
Am I out of line to think that visiting time should be scheduled when he is actually doing the parenting and not putting it off on his GF?? He has said that only coming down to have dinner with them during the week is not quality time but I am not seeing how spending the day at his house without him is quality time and am I supposed to give parenting time to someone who is a stranger to me?
