You hear of very rosy courtships that resulted in crashed marriages, after a few months, people say its the stormy courtships that produce marriages that stand the test of time.But how much storm should u really stand in a courtship( how do you tell its not worth the trouble any longer?)

It all depends on God and ur tolerance i feel the stormy courtship
lasts longer than others because you two must have passed thru alot together
and solved certain issues

It's a personal decision as to how much storm you choose to deal with. But sometimes it is hard to tell whether it will work out. You go with the flow and see what happens. You put yourself out there and sometimes it works out, sometimes it doesn't. But yeah, I feel you. It is a very hard decision sometimes deciding when to stick to it and try to make things work and when you should finally just walk away.

Like curiousNja said, it's hard to tell. But you can make your safest bet that it will work out if you see that are really really compatible. As in you have the same interests, think alike and agree on most things(definitely not all things) so you don't have to disagree much. The probability that this kind of relationship will work out is higher than when the two of you are parallel lines!   Again, I have to say it's hard to tell!

Its one day at a time.

Just take it like that, and for your relationship to "work out" really depends on the commitment you and your gal are ready to give to it.
