Forbidden Love

I have a friend..a close friend of mine…He is having a problem in finding a suitable girl to be his soulmate..

I don’t really understand his problem but he always get to know a girl which is under engagement status. (Fiancee)

FYI, it’s not only once he got to be involved in this kind situation, but it seems to be repeating and looping all over again.

Why he keeps bumping into other people’s fiancee?

And he’s not getting closer to any single girl…

And for the fiancee also, why do they keep giving false hope to a single guy like my friend?

Any opinion guys?What shall he do to solve this?
