from someone who has been married 25 years and ONLY ONCE ..... there are alot of things to look at before comitting to someone. You weight their GOOD points and the BAD points as you date. But there is one point That is make or brake if you really want the marriage to last. HONESTY of the HEART/Soul
The ONE THING you want in a spouse is true HONESTY of the HEART or LOVING YOU and ONLY you , after a while of being married I realized that IS the one thing That is most important and it takes along time to LEARN this. Looks , intelligence, mannors, working hard , smart, personality are all important. ..but for the marriage to last you got to "BE TRUE".... she/he can be a theif of money , but not be a CHEATER of the HEART.
If the person is TURE and HONEST of the Heart , then the rest other shortcommings can be dealt with in time.
Another lesson , hard one I've learned is this .... the apple don't fall far the tree.
Look at the parents.... if they are cheaters and been married a dozen times and flakey , good chance the kids will be the same.
Lastly DON't marry somebody who REALLY don't love you . You may be crazy over them, but if the same isn't true in return ...its not going to work. Somebody is marrying somebody for the wrong reason.
