DEAR ABBY: I am a divorced mother of two teenagers. I’ve been seeing my boyfriend, “Sean,” for almost five years, and when the pandemic started, he moved in with us. I am supposed to share custody of my teens with their father, alternating weeks. However, his job requires travel, and the kids are with me more often than not, with little to no notice. They are also reaching an age where they don’t really want to go to their dad’s all the time.
