I have a crush on my boyfriend's twin!!!

I met this guy a few months ago who looks almost identical to my boyfriend who I have been with for a few years.

(Everyone including them think they look the same as well so its not just me)

We have been talking a lot as friends but since I first saw him my heart would race and I'd get butterflies (LOL)

He also has the same personality as my boyfriend when we first met and he has told me that he has liked me since he first saw me.

I would never cheat on my boyfriend although I'm finding it really tempting because they are so alike except this new guy is more nicer to me than my boyfriend because we have obviously been together a while and the butterflies and heart racing has worn off..

It almost feels as if I have gone back in time to meet my boyfriend all over again, I'm not joking its so weird they can pass as twins! and the whole time I'm talking to him I just wanna jump him and I can't concentrate when I see him I instantly start thinking dirty things and he knows this so he keeps coming on to me and telling me to leave my bf.

I would never do that to my boyfriend so I have not been talking to this guy as much but I can't help but think of him all the time and I feel bad for my boyfriend but if I see a message or something from him I get so excited like when you start going out with a new person..

How do I forget about this guy?

Its hard too because when I look at my boyfriend obviously I think of him and I kinda start to miss him!
