I need advice...

My boyfriend and I have been dating for almost 2 years, I am in love with this man and I would never do anything to hurt him on purpose. But something is killing me and I don’t know how to deal with it. My best friend and I have been closer than ever he is a really great person and things have been escalating slowly. I hung out with him yesterday and I noticed how there was a lot of tension, and we were too close to each other and we’ve never done that before. The thing is my guy best friend is one of my boyfriends closest friends too. After hanging out he texted me that at the park he wanted to confess his feelings for me but he doesn’t want to risk losing anybody over the feelings he has for me. At first I wasn’t sure how to respond but I was never mean to him or anything like that. Here’s the thing, I have always known I had an attraction towards him, but I always brushed it off because I know I would NEVER hurt my boyfriend that way. My best friend and I talked about it all night because we wanted to clear the air, I came clean to him and so did he. I thought things were only going to get better after that but now I feel even more attracted to him. I am not going to pursue anything with him because I really don’t want to leave my boyfriend but this whole situation is confusing me and I feel horrible. We are planning to maybe stop talking for a while so we can focus on ourselves and not cause any harm to each other or anyone around us. I don’t want to stop talking to him because I would really miss him but maybe it’s for the best. I’m not “cheating” or anything like that god no. But I’m so confused and I’m not sure what to do..... any advice??

(Sorry if this upset anyone and I’d appreciate no hate I just need some honest advice...)
