I think It depends,
How close is close ? I mean do you tell this person all your
sorrows, you won't tell your spouse ? Do you feel that this person
means alot to you ? Is this person one of your best friends -top 2
? Then I believe, You cannot be close friends without restrain..
because time can nurture love.
Restrain may be due to commitments to your spouse, It could also
mean it's a one sided affair or simply confused, afraid where it
lead to or end. I mean if one is married, and are close friend for
many years where timing sucks and they has no opportunity to
develope this relationship, may be due to self-confidence or
interior complex from one party, or simply job commitments.
Honestly, how many EX can be friends without the other feeling odd,
and I do not mean relationships that ended due to ailing
love.
It actually the same.
I know from experience. I even wrote a letter to her, that our
friendship would end, when she married. I was out-stationed for two
years, I knew her for close to 15 yrs then. Due to my inferior
complex, family financial problems in my earlier years. I really
regreted not pursuing her earlier, when she hinted. After that,
well, Timing also suck, she's attached when I'm not. I'm attached
while she's not.
The letter I wrote is truly moving, it was written after her
wedding dinner, It was wrtten with my soul. To this day, I do shed
a tear or two reading it.
