Getting someone to love is the easy part, it's sustaining it and keeping it that is where the trickery lies. Sure, if you're not accustomed to this then it'll throw you; it's a lot of work and trial and error - but it gets better. It's never perfect and it never will be, but it's still pretty damned good all the same. Accept that you're each half of something, and that you need to be willing to evolve WITH someone in your own way and encourage him evolve as well. You may not always end up at the same place, but that is okay - there's always catching up. Remember to give each other space, and learn when to leave each other the hell alone now and then. If you don't give him the opportunity to miss you sometimes, why should he? Never put more responsibility on him than is fair and separate what is important from what it petty and won't matter in a few days time. It's hard work, you'll either do it or you have to wear the t-shirt that says "I'm a great big pussy & I have no balls".
I met a woman
She had a mouth like yours
She knew your life
She knew your devils and your deeds
And she said
"Go to him, stay with him if you can
Oh but be prepared to bleed"
Oh but you are in my blood you're my holy wine
Oh and you taste so bitter but you taste so sweet
I could drink a case of you darling
And still I'd be on my feet
I'd still be on my feet.
- Joni Mitchell; A Case Of You
