* मुझे तुम्हें देखने की इच्छा है। (Mujhe tumhen dekhne ki ichchha hai.) - This is a slightly more poetic way to say it, and is also informal.
More affectionate:
* मुझे आपसे मिलने की बहुत इच्छा है। (Mujhe aapse milne ki bahut ichchha hai.) - This means "I really want to see you."
* मैं आपकी बहुत याद कर रहा हूँ। (Main aapki bahut yaad kar raha hoon.) - This means "I miss you very much."
Note:
* The word "आप" (aap) is a more formal form of "you," while "तुम" (tum) is more informal.
* The verb "देखना" (dekhna) means "to see," while "मिलना" (milna) means "to meet."
* The phrase "इच्छा है" (ichchha hai) means "want" or "desire."
The best way to say "I want to see you" in Hindi will depend on the specific situation and your relationship with the person you are talking to.
