I’m confused

Ladies I have been with my boyfriend for 3 years, though our relationship isn’t what I had in my mind as my fairytale ending I do love him. Now there’s this our guy who came into my life and I was hesitant about getting friendly with him, I did. Which I know is wrong, but I hung out with this guy once after he persistently kept asking to met, and I felt a connection like never before. He is the sweetest person ever nothing like I expected, I know this is just one experience but the little quality time we spent together felt perfect. Now I’m taking omg what did I get myself into, and what if this guy is the one for me, my bf rarely ever makes me feel the way I felt with this guy. 😫😫😫😫
