My brother's first wife has been in a committed relationship with her partner for about 33 years. I know that same sex relationships can be stable. However, the data is clear they are less likely to be stable than other arrangements. That wasn't the point.
I was trying to suggest that even romantic love can be less than we hope it to be. And, yes you will find a relationship that is everything you are blooking for even though as you say falling in love will result in falling out of love. That is an important perspective that I didn't know you had. You sound much better in your response than in your original post.
May God be with you in your search.
