Who woulda thought we wouldn't be together forever.. blah

I'm all grown up kinda and I'm ready to get another tattoo over it.
It's been many years with different ideas and I've got it now with a few things up in the air.
Here's the pics:






2 things to figure out:
I wouldn't even think twice about the heart with the white ambulance/paramedic cross in there except for that's it's hard to produce white with tattoos (bunch of stuff about skin colour and the white ink being overwhelmed with your natural melanin.. apparently it's harder to produce white with darker skin and/or keeping the white ink, white). You can read about white ink with tattos here.
I'm 99% sure of going with the heart with the cross without any colour if white is not an option.
The other thing is which way the tattoo should go. I like the placement of my current tattoo. With the new tattoo, the top portion of the escalator is going over the name.
If we go upwards towards the left we have good placement except for the heart. It might be too high and off to the left too much.

Now if we go upwards towards the right, the heart might be too much towards the middle.. kinda wanna keep things on the centered on the left.
My initial plan was to go upwards towards the left but I'm 99% certain of going upwards/right.
Any suggestions/comments would be greatly appreciated.
I'm going to let it sink in for a few weeks and we'll see what happens.
