I'm not an expert but been married a long time and we have good and bad days.
We're not the kissy type but hug, hold hands, etc. We tell each other we'll be lost if the other dies. Part of loving someone. We have a lot in common which is why we stayed together.
I grew up fantazing about romantic lifelong love. Its like that in the beginning but doesn't last. Instead you become each others very best friend which is awesome.

I don't know. I will say it exists, but you also have to know they are their own person too. They have their moods, as do you. Communication really helps in these aspects. Relationships really become difficult when someone feels parts of them are not being fulfilled. And it's finding a page together where you understand each other or even better never have to ask.

It definitely exists, but like you said nothing is perfect.
You both have to be willing to accept the other. Flaws and all.
That's what real love is, a dual effort.

The consistency is in the commitment. I could go on for hours on how good our marriage was despite some serious issues; some financial but mostly health.

Even when the dementia began during the lucid moments I knew that the commitment was still there. I just hope that in those moments she realized the same.

Yes, those relationships exist, but all of us have occasional bad days and need to be forgiven if we fall a bit short on showing our love.

It's a real thing that does exist..
But it's something that has to be done with intention

I don't think it exists.

Yes l had that for 18 years!
