It's not in Russian :)
It's a mix of weird words seemingly with no sense at all.
OK, the first line: Будешь ть: - will you (be?)
the second line: no Russian words at all (Phonetic symbols instead) something like ... coming with me?
The third line: Союз... прил (conjunction... adj)
the fourth line: красивый сущ предл (beautiful noun preposition)
the last line: no Russian words
Addition to In's answer: person who wrote it, tried to copy Russian letters without knowing how to write them (and even without knowing which symbols are separate letters and which ones are part of one letter) and without knowing what he writes.
i'm afraid your boyfriend doesn't know russian at all
No i can′t.I am sorry :(
But try it in the Word Reference!
