sexuality

so i me and my boyfriend have been dating for awhile and hes aware that im curious about my sexuality but it makes him somewhat angry. but i feel as if im not happy bc ive been feeling this way since i was in elementary school like i knew ive always had an attraction to girls also i just never explored it bc i was scared then i got into this relationship 3 yrs ago and this yr is when i finally talked to him about it but now i dont feel comfortable talking about it bc ik it makes him feel some type of way . idk what to do. i even promised id never bring up my sexuality to him in an argument bc he didnt wanna hear about it.
