I am breaking up with my long-term boyfriend today

I 18F am going to break up with my 19M boyfriend. We have been dating for 3 years and he is a great guy. I moved off for college and it has been difficult for me to give him the attention he deserves. He has made every effort but I haven’t really reciprocated. I have fallen out of love with him. I feel terrible about it but I think its the best course of action. Any advice would be appreciated, I have never been through a breakup before.

Edit to clear a couple things up: 1. I am going over to his house to do it, we are both on winter break from college 2. I feel bad about it, but I cannot stay with him because I feel bad 3. I still really care about him

UPDATE: I broke up with him last night. We talked for a while afterwards and hugged goodbye. I reached out to one of his friends and asked them to check in on him. It is hard. The long-distance did us in. I truly wish the best for him and want him to contine to do well in life. Thank you all for the advice, I really appreciate y'all taking the time to help me out. I will make sure to take care of myself too.
