My girlfriend is cheating on me right now… and I’m watching it happen 💔

I never thought I’d be in this situation, but here I am. I’ve been in a committed relationship with someone I gave everything to — emotionally, mentally, financially — and now I’m watching her stay overnight at someone else’s house. I had this gut feeling something was off. She lied to me about where she was going, and I’ve been quietly watching her location because I didn’t want to believe it. But the facts are there: she’s been parked at the same random address for hours, after midnight, not answering my calls, and not where she said she’d be.
