When we meet the right person to love when we're at the right place, at the right time. That's chance.
When you meet someone you're attracted to, that's not a choice. That's chance.
Being caught up in a moment (and there's a lot of couples who get together because of this) is not a choice, that's also chance.
The difference is, what happens afterward? When will you take that infatuation, that crush, that mind-blowing attraction to the next level? That's when all sanity goes back, you sit down and then contemplate whether you want to make this into a concrete relationship or just a fling.
If you decide to love the person, even with his faults, that's not chance. That's choice.
When you choose to be with a person no matter what, that's choice.
Even if you know there are many people out there who are more attractive, smarter, and richer than your mate, and yet, you decide to love your mate just the same, that's choice.
Infatuation, crushes, attraction comes to us by chance. But true love that last is truly a choice. A choice that we make.
Regarding soulmates, there's a beautiful movie quote that I believe is so true about this--"Fate brings you together, but it's still up to you to make it happen." I do believe that soulmates do exist. That there is truly someone made for you. But it's still up to you to make the choice if you're going to do something about it or not. We may meet our soulmates by chance, but loving and staying with our soulmate is still a choice we have to make.
