Wanting to get and staying married.
I was already pregnant when my husband and I decided to get married. I was only 22 and he was 21. I knew getting married at that time wasn't the greatest idea especially with the pregnancy and all. However, I did feel that I could actually grow old with my husband.
I think there are 2 points to consider when a couple decides to marry.
1. Can you really grow old with this person? Being in love with him is important too but when you're old and gray and you see your spouse grinding his teeth and food dropping out of his mouth while eating and talking at the same time can make a huge difference. No one stays in love forever. Love will always be there, but in a different way. So if you see yourself 30 or 40 years from now and still wanting to be with the person then go take the plunge.
2. It is not always about the money. When your boyfriend or girlfriend tells you he/she can't marry you because he/she doesn't have enough money yet, it only means he/she has no intentions yet (or not). Even if you have a penny in your pocket but believe you can make things work out with this person, then surely it means you can go on living with him/her for the rest of your life. I am pretty sure a lot of married couples out there fight about their finances but if you consider yourselves beyond that, then the marriage will work.
A lot of things change when children are involved too. Sometimes when you feel you just can't take it anymore, you take your children into consideration before deciding to part ways or to stay together.
I am happy to say for 10 1/2 years now me and my husband is still together. We might not be the happiest, richest or healthiest but we make things work out with 3 children in tow.
