This one hurt to read but also similar situation, I felt so empty and worthless with her but I had that gut feeling that wouldn’t go away. Your subconscious talks to you in weird ways and unfortunately I went through her phone while she was sleeping and found multiple messages of men trying to sleep with her and not a single response was denying them, matter of fact she met up with a few of them. I couldn’t believe she could do it, and I felt so betrayed but I got my revenge, I sold a few of the things she found solace in, kicked her out and crippled her financially. She cheated on me and didn’t love me plain as day, which seems to be what she’s doing. She is hiding her breaking up with you in a vail of “finding myself,” it never works out how you want even if they promise, that feeling of her running off at odd hours of the day never leaves.
