When. Does it sound like I love my boyfriend stillto you?

This might be quite long but I’ll try and make it short. Basically me and my boyfriend went through a rough patch (please don’t give me hate or anything) and I cheated on him, I had to go on a break because of this to sort my head out. Anyways my boyfriend knows about it because I told him and we had a chat about everything and he found it in his heart to forgive me which I am so happy about! But I can’t help but think about this other guy he’s always on my mind and last night after a few drinks my boyfriend brought the situation up and I told him I’m obviously still thinking about this guy even though I don’t want to and he said we will get through this just don’t think about him its easier said than done though isn’t it. I love my boyfriend I am happy he forgave me but I don’t feel happy and am thinking about this other guy all the time. Basically what I want to know is what would you do? Or has anything like this happened to any of you before? Thanks
