How to break up with someone you love

I love him still, I do so much.

But I have this urge to see and sleep with other people and I’ve tried bashing it down so many times but it just keeps coming back....

I haven’t cheated on him, and I don’t want to but I just can’t help but have this intense feeling that I’m missing out and don’t want to be committed at the moment- I’m only 16 and it’s the perfect person at the wrong time.

We’ve been together for a year and about four months.... and I do love him and he’s the perfect most kindest most caring person, he’s never done a single thing wrong or hurt me or anything, We’ve never has any serious arguments other than like little ones if one of us is acting out of order.

I just feel like if I stay with him I’m going to end up fucking it up.. and I don’t know whether it’s easier on him if breakup now, or if I do it and make him hate me so it’s easier for him to get over me....

I just want to breakup with him in a way that’s as easy on him as possible.... I’ve even debated trying to become a shit girlfriend so he doesn’t want to be with me anymore... I just don’t want to hurt his feelings but I know that’s almost impossible :/

Please help, what might be the easiest way to do it? He keeps asking me if I still love him and I say yes because he’s on holiday and I don’t want to hurt him , and I do still love him, I just don’t know if I want to be with him :/ and I don’t trust myself to not hurt him :/
