Ok yes I'm trying to learn Arabic, but in Lebanese dialect!!
I'm interested in learning it written in English letters like this
"Mar7aba" Not like this "مرحبا" it's waaay to confusing.

Hello
"Mar7aba" it is not arabic language ,it is chat language, so if you use it you can not read arabic
I advice you to learn arabic letters it is just 28 letter and in english 26 letter so that is very easy because if you learn real arabic you will be able to read and write easily
Best Wishes
