It may sound romantic when people say how alike you are, but actually it’s your contrasts that make you a strong couple.
And if your relationship can’t survive that level of honesty, then it’s time to get out before you get completely swamped.
Remember that wonderful song: “I can’t live, if living is without you!” It sounds like such a lovely thing to say, but have you ever actually said something like that to someone? And meant it? In real life that isn’t love, it’s desperation.
The first time your partner heard it, it would certainly have sounded romantic. But sooner or later that level of intensity in a relationship becomes unbearable. Especially as it implies that you’re behaving more like a child than an independent adult.
