Wh iniated talk on kids meeting ow, on my weekend, said no, went mad asked wh to leave.
I'm D'd with a good co-parenting relationship. I'd make an exception to our custody schedule for a distant relative or a vacation, but never to meet some "om" or "ow". Never heard that one before!
For Mother's Day I encourage my kids to think about and make or buy something for their mom. That teaches the kids about gift-giving, holidays, and thinking of others. Okay, I like to see their mom happy, too!
I'm so sorry for where you're at. Really rotten treatment by your ex--seeing someone else AND having an intimate relationship with you at the same time. Take care.
