How do I (24F)move on from a crush I’ve had for months while being with my bf (31M)?

hey ya’ll. Ive already been feeling a lot of guilt and shame for many months so please go easy on me . I’ve been with my current partner for 3 years and throughout the entire relationship we’ve had compatibility issues. I love him with all my heart , he’s been there for me and supported me through many changes in my life. He’s my best friend. However, He’s not the affectionate type, he also isn’t the type to offer reassurance when I ask for it . I, on the other hand, need a lot of physical affection, words of affirmation , etc. Throughout our many fights I never felt completely satisfied after it was settled . It was always something I had to get over meanwhile he’d completely fine waiting for me to get over it . I know this is very vague but I would be typing entire books if I’ve had to explain our fights. There’s been multiple instances where he gets so frustrated he kicks me out of his place, and he’s raised his voice, has said hurtful things to me.. I’ve realized that I’ve been resenting him from these intense fights and it’s been building up inside . Despite my love for him , I felt myself emotionally detach and I’ve started to fall for this guy I met about 8 months ago. He’s honestly everything I’ve wanted in a partner. We clicked instantly and we have almost everything in common.. he’s a great communicator, he listens to what I say and asks me so much about myself. I feel like he really sees me for who I am. Not to mention he’s family oriented, we have lists of things in common, he’s funny, so sweet. I’ve never felt this way before not even with my current boyfriend . He has confessed his feelings for me recently and I’ve honestly felt awful with guilt that I feel this way. I’ve never thought this would happen to me . The thought of leaving my current boyfriend makes me feel sick. I don’t know how to move past this if I even can. I’ve read having a sit down discussion with him about this is necessary but I can’t even think of how to word this. I’ve told my boyfriend before I feel resentment from all our fights and he’s told me he will try to be better and watch how he says things to me but, I’m not sure if that’s enough of a conversation.
