You love each other. That was never the question.
The question is whether you know how to make each other feel it. Love is a feeling. A relationship is a practice.
The gap between having the feeling and doing the practice is where most couples get stuck.
You can love someone deeply and still make them feel alone. Not because you're doing it wrong. Because nobody taught you how to translate what you feel into what they need to hear.
Most couples don't show up to therapy because they stopped loving each other. They show up because they stopped being able to show it in a way the other person can receive.
That's what therapy is for. Not to fix something broken. To build something that was never there in the first place. A shared language. A way of reaching for each other that actually lands.
Love is the easy part. Learning how to make someone feel it — that's the work worth doing.
