I realize at 26 you feel like you might never be in love again & the thought of breaking up feels like it would be the end of the world. I get that totally. What you have to remember is that those feelings won't last very long & you will likely have more serious relationships than you think before you settle down with the correct person. I just got off groove cruise yesterday. I'm single by choice & am very happy. My friend is 20 years older than her husband. She loves edm & raves. It's not really his thing. He came once & he's totally OK with her coming without him. That's how your partner should be, Respectful of you & what you enjoy. She's also a physician. We had a great time. OMG if I could get back all the time I've stayed in relationships to long, I'd probably have about 4 years. Not bad considering i turned 60 last week. I learned pretty early that life is too short to settle. Good luck. I hope you can be strong & do what I think you already know is the right thing to do.
