This revelation has left me heartbroken. I'm struggling to understand why she's upset that I'm not happy about it. Our relationship was solid, with no signs of trouble. I am trying my best to process this new information while still being supportive of her.<br><br>I want to help this person! So how do I do it?<br><br>UPDATE: She dumped me anyway and when I mentioned I was gonna stay with my dad for a few days I was shit on. I'm just done.
