Relationships last not because they were destined to last. Relationships last long because two people made a choice to keep it, fight for it and work for it.
It takes work and dedication from both.
I gave on that a long time ago! One is always willing to do the work the other gives up! I love being single!
Two people have to make it work and have to want to. Think what made you fall in love in the first place.
But sometimes you have to let it go if it go when it's beyond your control of making it work.
If you really love each other, you will stick together until death do us part. No explanation.
