Yes, love is always enough to keep a relationship together. Real love is, anyway, not what passes for “love” in our superficial, materialistic society.
This isn’t “naivety”. “Naive” implies ignorance and/or lack of experience. I know this to be a fact, from watching other couples as well as experiencing unconditional love and devotion firsthand: Love is always enough, because love is the point.
Stop referring to the failed relationships of others and yourself to support the idea that “love isn’t always enough”. Not all couples are the same. There are successful couples who prove time and time again that love is enough by consistently putting their love first at any and all costs, without even the slightest regard for anything that threatens to come between them.
To say “love isn’t enough” indicates that there is something more valuable to you than love. Not all couples have this problem, though. Love is the be all end all for many couples. It’s more than “enough”; it’s everything for them.
No pain, disagreement, wrongdoing or consequence can interfere with real love. Your lover should mean more to you than your ego. Your lover should mean more to you than your values. Your lover should mean more to you than any perspective. Your lover should mean more to you than any other ambition, need or desire. Your lover should mean more to you than any (and every) other person. Your lover should mean more to you than happiness and/or health. Your lover should mean more to you than survival itself. Nothing is more important than you, so there’s nothing worth contending against you on behalf of or walking away from you for. You are my big picture.
If something threatens your love, discard it. If you want to walk away, don’t. If something tempts you away from your partner, ignore it. If it hurts, endure it. If it’s killing you, then die. Always choose to be with your partner, at any and every cost, whether it makes you happy/healthy or not. Have no deal-breakers.
Love is always enough, because love is the one, only, and entire point of this life and everything in it. It is the be all end all. Nothing comes close to mattering even half as much. Recognize this, get a partner who recognizes it, and you’ll be one of those couples whose love conquered all until death took them out of this world.
Love is the point of being together, and being together is the point of love.
