Agree with you, as long as they aren't staying together just because they are too comfortable.
I have seen quite a few times couples who ares together 5 or more years who should have called it quits after about 2. There is nothing worse than people who just make each other miserable rather than moving on.
There is something about sticking it out though, that I'm more and more aware of as I get older.
When I ask the people in my life who I think have the strongest marraiges, they all have said something "happened" or changed in their attitude/ feeling to their partner around btw yr 15 and 20 and had a very positive change in their relationship. At 17 years, I'm looking forward to experiencing that! I think my husband has in the past couple of years and I'm laggging behind a bit.
My parents were married for over 50 years, most of it relatively unhappily. But they "got the hang of it" after about 50 years and the last 5 years or so before my dad died were the best years of their married life (maybe apart from the first couple of years.... we just found photos of their honeymoon and early years that we hadnt seen before..... ..they clearly enjoyed themselves then!).
I think its that the commitment to the relationship and, for those who have done so, the vows they have made, even through the difficult times, which can create a depth in the relationship and in your own person, which is stronger than if you move on.
I think we all make each other miserable, to a certain extent.... its iron sharpening iron! But if we bend and allow ourselves to be changed by our partner and for our partner, then only good can come... it might just take some time!
BTW, I agree with Peter that, while this thread is interesting, that Amazing Angel might find her interest in dating/ married better met on a different forum!
