"Love between souls" last longer than anything else. If only we sincerely keep thinking and act in accordance of what positive changes and improvements can we bring in the life of our spouse, instead of expecting anything in return, our married life achieves a meaning worth living for.
Every good action has at least some good reaction, sooner or later. If one leads by example in every field of life, by keeping oneself busy in satisfying the legal needs of one's spouse with sincere prayers and having faith, inshaAllah sooner or later s/he would be able to see in his/her spouse what s/he always desired / wished for.
May Allah (swt) bless us with the wisdom and strength of consuming all our energy on positive thoughts and actions in favor of our spouse with least (humanly possible) expectations.
