Answer

There will be a word touch him for sure without anyone 's feeling

لا بد It's equal -will for sure - somehow.. or -must-

Answer

you don't have to translate it literally, you can understand the sentence and put it in your way

she hadn't let him go because there was always a word that only him whom can feel it

Answer

لا بد
They are two words, 
لا means No
بُدَّ 
May mean literally Escape, 
When they come together "as they do mostly",  they mean "Must" 
لا بُدَّ أنْ / لا بُدَّ أنَّ / لا بُدَّ وأن : حتمًا أو مِن الضروريّ
Or they mean No Escape, when you talk about something should be done and you can't escape it. In another meaning "it can't be helped ".
