Hi Guardx,
I sympathize with your previous plight and I'm glad you've emerged
a better person.
I would agree that both parties need to demonstrate commitment to
the relationship, and it's not just one party.
I think we have seen countless scenarios here where one party does
not want the relationship anymore, and the Threadstarter, be it guy
or girl, is always like grasping for air hopelessly.
Your point is that if the girl is going out with another guy, it
signifies a loss of commitment, and at that point of time, it's
like a total emotional break.
Your ex-gf is a girl who has little qualms about sleeping with
other guys, and show little moral responsibility in any
relationship, be it with you or with the next guy or guy after
next..., and you are better off without her anyway.
Unfortunately there are girls (and guys) like this around... When I
was in the army, I called up this girl I like everyday (we have to
queue for the coin phone then), and she gave me the impression that
she liked me as well, until I realised she had a boyfriend for
several months.
But not all girls are like this.. Perhaps TS's girlfriend is only
trying out and is still working hard, and I thought every situation
is different.
By the way, I was the "other guy" 10 years ago to my girlfriend,
and she went out with me whilst still in the relationship with a
hopeless guy who didn't even do anything for her birthday and only
wanted to do physical stuff. But she gave him plenty of chances,
and he didn't take it nor want to change anything. So I "won" her
over and gave her a better life which I think she deserves.
But your situation is still a good reference for TS, I
believe.
Take care!
