I have a problem with my boyfriend..Please Help?

I'm Lacey. And, I am currently in a relationship. But. There is a problem. The boy of my dreams left me about 4 months ago. And here is what happened. I met a guy names Roy. Roy would call me all the time..even at 4:00 in the morning, just to leave me a voice mail saying that I was beautiful. Now, we talked..For what. 3 months? We only met once, and he wasn't sure if he was ready to go out, considering we didn't really know each other. Yet, we talked all of the time. I cried with him, and laughed with him. I felt like I was - in love -. Then. After those AMAZING 3 months... he stopped talking to me. He told me I pushed him away. ( Also, we had about a 3 hour long conversation the week before about him NOT leaving me. And he promised he wouldn't ) We talked about a month after that...and we argued. No you started this ****! YOU LEFT ME! NO YOU PUSHED ME AWAY. ( And so on. ) It's been about a month since THAT happened. ( We haven't talked since ) This guy asked me out..adn we had been going out for 3 weeks now. He saw on my computer a old conversation I had with Roy..and KNOWS I still have SUCH strong feelings for Roy. Like..I feel like I'm still in love with Roy ( Even though we don't talk anymore ) My friends say it's rude to go out with this other boy because I still like..love Roy. ( Also, I will be like " I like you SO Much to my boyfriend..and he would crack things like, " Not as much as you like Ruben " And stuff..:// Is this rude for my boyfriend now? ( I also NEVER talk about Roy in front of my boyfriend. Even though my boyfriend brings him up QUITE A LOT. )...What should I do? ( It has also been about 5 months since me And Roy stopped talking..and I'm not over him. At all )
