One can never seek love, looking for
lifetime partners. For love, at times, doesn't provide lifetime
partners.
I don't blame you for looking what you seek, as our biological age
and cosmic lesson are vastly different. Even if I am 40 and
unmarried, I will tell myself so be it. Probably throw myself into
spiritual learning in substitute for relationship deficiency.
At that age, you will probably be desperate. Age is catching up and
it seemed that any relationship you land on would immediately view
as a potential for marriage, regardless of how it seemed like. This
poise a dangerous thought indeed, as relationship at 40 is the same
as relationship at 20. Those constant never changes.
I remembered an old case where this man remarried thrice. Checking
him out, it was discovered that his mindsets plays a huge reason
why those marriages never last (apart from serious astrological
affliction in Love and Marriage). I dont know you, but marriage
should only come during the apex of your Love. Any marriage due to
biological/other reasons place a cap on fulfilment and contentment
gain from the Love. This man became so desperate that any girl he
hook up, he thought of marriage, even if they are unsuitable.
He thought he was running out of time, only to realise that he has
delayed himself longer through his failing marriage.
What is running out of time? What was he trying to run away from?
Age?
A state of mind.
He created the sense of urgency... he got killed in his sense of
urgency.
Can love be rushed and artificially made?
I suggest the same thing as I would to a 20+ young lad - to expand
social circle, adopt new interest and do alot of reflection. I may
not understand you as much as yourself, so WHY have you landed in
this state, this enlightenment may save you alot of time on
repeated lessons that ought to learnt ages ago.
There are no short-cuts to Love and when you seek for easier route,
you get compromised quality of your own relationship. 
Cheers
