Is it wrong to stay in a relationship if you're not completely sure about love?

I don’t feel that intensity, butterflies, or that rush you get with them when you’re super happy or super sad. Things are comfortable and great but there’s no adrenaline, no fights, and my partner is passive aggressive. Last time my partner was less affectionate and kind of ignored me when we disagreed on something but rather than confronting it, my babe ignored it and it made me sad.
