It's the most commonly asked question and was probably answered even here. I just copy with my edit from somewhere else.
You can write like this:
Here's it is with some diacritics to distinguish between male and female forms:
Modern Standard Arabic (MSA) or FuS-Ha الفصحى
أنا) أحبكَ) (ana) uHibbuka (to a male)
أنا) أحبكِ) (ana) uHibbuki (to a female)
The standard Arabic language is hardly used by Arabs in informal situations, so everyone speaks their dialect, for example.
Levantine or Egyptian
أنا) بحبَّك) (ana) baHebbak (to a male)
أنا) بحبِّك) (ana) baHebbek (to a female)
The capital letters stand for a slightly different sound, in case you wonder why I capitalised some letters inside words. If you are not trained, you can pronounce H (ح) as h and S (ص) as s.
