If I understand correctly, your case is different from all the
above mentioned. In the above, people wanted to get out of the
relationships - and will initiate the break-up. In your case, you
are afraid of getting out.
So....for your case, maybe you have to try a little rekindling. For
me, usually a little break, being in a different world and
different atmosphere helps. For example, take a short holiday to
some beach resort, try doing something different (different places
for meals, meet at different times, etc), etc.
I feel that the concept of endless love is a very ambiguous,
contraversial and subjective thing....
