My wife would get really annoyed/upset if I had anything to do with another person, esp. a female.
Sandi is spot on. I'm sure it would be fun to tell her you're on a date, and can't talk with her, or apologize to her later, because you're other girlfriend and you were out... but lying won't help. You're end goal is to save things, right? Just going dark - let her feel that darkness, except for strict kid handoff/safety stuff.
If she's texting you that kid said 'daddy'... that's her doing a sonar 'ping', checking to see you're still where you're supposed to be. It's time to go stealth on her - engage the catepillar drive. *crosses fingers, hopes people get the reference*
