Should I tell my boyfriend that I still have feelings for my ex?

Nicole Carrington Asked: Should I tell my boyfriend that I still have feelings for my ex?

Me and my boyfriend have been dating for 5 months, we're both 15. He's very emotionally attracted, I love him to death and all, but he freaks out when I talk to guys and stuff. These past few weeks I've been thinking about my ex a lot… He stole my virginity, and I know he's not good for me or healthy for me at all, but despite that, I can't shake the feeling from just a year ago. I miss it, and I don't know if it's because things are getting rough with my current boyfriend or what. We fight all the time and he gets very angry easily and my friends don't think he's good for me but I havent listened… So today me and my ex started texting again, and I told him how I've been feeling for the past few weeks and that I still have feelings for him and he said the same. Well now I feel horribly guilty because that's how I get, but flirting is considered cheating in my bf's eyes. I know if I told him it would hurt him unbelievably and he'd probably end up cutting again. He's so sweet and loving and caring, and I feel like I need to tell him, but I already promised my ex that I wouldn't tell… But I feel horrible. Something is telling me I should talk to my boyfriend and tell him, but another is saying that I should forget about the feelings completely since I didn't actually cheat. Some advice please?
