My GF is "networking" with her ex on LinkedIn and says I’m being "unprofessional"

my gf (27F) has been grabbing "coffee meetings" with her ex because he’s "in the same industry" and "has good connections." they’re constantly messaging on LinkedIn. i told her it makes me uncomfortable and she literally laughed. she said i’m "stunting her career growth" and that i’m being "toxic." am i tripping? since when is an ex a "career mentor"?

The Breakdown:

• She Said: She’s being a "Girlboss" and maximizing her network. She views the ex as a tool, not a person.
• He Said: He sees a Submarine move. LinkedIn is just a "safe" place to flirt under the guise of "synergy."

The Science: This is Cushioning. Using a professional platform to maintain an emotional connection with an ex provides a "security blanket" that undermines the current relationship's stability.

The Solution: "I'm all for your career growth, but 'networking' with an ex crosses a boundary for me. If this is purely professional, let's keep the meetings in the office, not over 1-on-1 coffees. My comfort in this relationship shouldn't be the price of your 'connections'."
