I've been married for 14 years, it will be 15 years in May. This doesn't make me a marriage expert, but I can offer some insight to my own marriage.
Love changes, I love my Husband, but it's not the new what I've heard call puppy love. For me it's more, you're my best friend and I don't want to live without you love.
We know each other very well now and in many ways. We really do finish each other's sentences. Not all the time, but a lot of the time.
Relationships change with time. Unfortunately some wither and die, other's grow. You have to work at marriage. I don't mean break rocks with a sledge hammer, I mean keep it going. Date each other. I get mad at him sometimes, he has quirks that irritate me, usually I don't tell him. Except if he bite's his silverware when he eats, I can't stand that. But there are things about me that irritate him too from time to time.
We've had moments when we've been really angry at each other. We worked it out, talked about it. There was a time when I wasn't sure what was going to happen. I leaned on God heavily during that time.
Things also change when you have children. Not everyone wants children, we did. We have 2 and they are 7 and 8. When our Son was born, we were tired and clueless. He delivered News Paper's in the wee hours of the morning and then went to work all day. I worked a couple of days a week. Thirteen months after our son was born we had a daughter. Still did the same things with work. Eventually he got a better job, things got a little easier for us. We thanked God for everything and still do.
I hope we say married forever, we've talked about our Marriage vows and how serious they are to us and To God.
I hope I gave some insight to some.
God bless.
