You need only ask once. After that, just give thanks to the Universe that it has already happened.
"Dear Universe, thank you that ______ my love and I are in the committed romantic relationship of our dreams that brings us both complete happiness and 100% fulfillment!"
Drown out any negativity: if you have a little voice that pops up into your head, make your voice louder and shout back to it the above affirmation until you believe it.
Then Patience as the Universe moves things around to bring your desire to you. Now, this period shouldn't feel like waiting, because waiting is desperation. And what does desperation do? That's right - it's a negative vibe and it brings your desire AWAY from you! So we want to elminate any feelings of desperation. How do you do that? By filling your life with activities and things you love doing. Step 2 above - You HAVE to keep yourself constantly happy, engaged and filled with positivity. Even if you're sitting alone watching TV, find something to be grateful for: the energy to watch TV, the roof over your head, the rain streaming outside your window watering your flowers. Put a smile on your face, take a deep breath and just love being in the moment with yourself. That's it! But even better if you can get up and do that one or two things you absolutely love that we were talking about before. Know that your desire is on it's way and the happier you get, the better vibe you send out and the more available you are to receiving your desire!
Just trust that what you are seeking, is seeking you, so you don't have to chase it. Know that your love wants you and they are coming after you as you think, speak and visaulize it!
