I thought your boundaries were appropriate. Who knows if down the road you will be even more Zen and will invite OW8 for some tea, but today you did what was right for you and your family.
I know OW1 lives far away and has her own family so she might not be available to help him on weekends when he has the kids. I know my STBX has his girlfriend over when he has our girls I suspect because its a lot of work to do solo. They probably dont even know they are doing it, but I think some of these other woman are partially child care help.
Hang in there with work It aint easy working full time and being a mom but your job isnt forever and once you become more stable finacnically maybe you can figure something else out
