Dream where I was crushing on someone who isn't my SO?

I may just be paranoid, but I had a dream where I was broken up with my boyfriend and I was crushing on another guy... but my boyfriend was involved in the dream several times....also want to mention that I have dreams where me and my boyfriend break up and Im with another guy but then in the end we end up back together and it feels better being with him....What does this mean, or am I just being paranoid?
