<human>: So my girlfriend and I are close. We've been like a married couple since high school. Lately she's been super busy and works and lives a little ways away, and we haven't seen much of each other.

 One day she tells me she's been feeling weird about me lately, and starts to question her love for me. I told her to wait until we have more time together, and we agree to stick it through.

 Now she tells me she's been considering leaving me and has developed feelings for a new coworker, but tells me she still knows that I am the better choice. I love this girl with all my heart, but I feel betrayed and scared she's going to leave me. I don't know if I should try and win her back or pack it up and move it out. Is this normal in long-term long-distance relationships? Advice?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Gf is super busy in another city, losing feelings for me, growing feelings for someone else, but all is not lost. Do I chase her or painfully quit while I'm ahead?
