Here is my humble opinion.
I have no problem with someone dating someone younger than them especially at the age of 60.
Heather seems like a great person, however I would not have pyed any attention to her if she wasn't with paul.
I wish paul all the best and hope that he is happy, but if heather is in this relationship for reasons other than that she just loves paul, than I feel deeply sadened by that.
If anything it wouldn't be fair to the child, if they decide to have a baby,look how old paul will be when the child becomes a teenager, plus he has a grandchild that will be older than it's aunt or uncle. don't get me wrong it can be done and again I wish all the best to paul and think whatever choices he makes are great. It's no ones buisness to lecture sir paul on relationships and marriage.
I somewhat agree with what you are saying shinestar but not for the same reasons. Everyone's opinion is welcome here.
so long see ya never
