So to make an extremely long story a bit shorter, 2 weeks ago my fiancé came to me and said she wanted to have spontaneous sex with another guy. I was instantly taken back I agreed to keep her happy, and she said I could fool around with another girl. Our 1 major agreed upon rule was no getting emotionally attached to the other person. So I met someone a very beautiful emo girl, she’s covered in tats, piercings, and has multi colored hair (100% my type to a T). But myself and this other girl have been talking back n forth and things have gotten spicy a couple times (only thru text, we’re still planning in person). But she’s such a smart individual with an amazing soul, mind, and body. I’m scared I’m growing feelings what should I do? I’ve like talking to her everyday and ik it’s breaking the rules we set but idk why I feel this way. Pls any help at all is greatly appreciated.
