Yeah, I know that Serbian and Croatian are closer than Italian and Spanish. I meant I think Romance languages are close the way that Slavic languages are (like how Russian and Croatian, for example) - but no, I didn't mean that they're practically the same language; sorry if that was confusing.
I just looked at an online Serbo-Croatian dictionary and got this entry for love:
love = ljubav, ljubiti, voleti, voljeti
freddie, does that help?
Edit: 'molit'sia' is to pray in Russian, if I remember right. And to pardon is 'prostit''. So probably Bulgarian is similar?
