i’m so confused!

i’m 16 and i’ve been in the same relationship since i was 14, so two years obviously. My relationship is extremely stressful at times, much like a lot of other relationships, and it’s also amazing at times. i love my boyfriend with every fiber in my body, but he just has a very bad temper and tends to get upset at the most insignificant things. He ends up hurting my feelings a lot and i end up crying. That’s not really the point of the post, but i just wanted to basically describe my relationship and what i go through constantly. So a guy at my school, his name is Blake, i’ve had a crush on him since my freshman year, but i’m not stupid and i wouldn’t fuck up my relationship for any reason, so now i only admire from afar. Anyway, today Blake told me that he likes me i couldn’t stop myself from feeling happy and excited for some reason. i likes him before i even knew my boyfriend. I feel so guilty for still being excited, idk what to do. i dont have any intentions on leaving my bf to be with him, i just wanted to get that off chest i guess. should i be feelings guilty? i hâte myself fir even adding him back because now all i want to do is talk to him and ik i shouldn’t knowing that he likes me, but he knows about my boyfriend and he respects our relationship but i still feel terrible.
