About ものだから
ものだから is a strong phrase that is used when explaining something or giving an excuse for one's reasoning. This grammar structure can simply be thought of as an extension of から 'because', with the noun もの 'thing' having its usual role of emphasizing what is said before it. Common translations include 'because (A)', and 'the reason is (A)'.
ものだから may appear directly after verbs and い-Adjectives, or な-Adjectives and nouns that are followed with な.
Occasionally, ものだから will be abbreviated to もので, or もんで, without any change in the overall meaning. The change of だ to its conjunctive form で indicates that there is something coming after, despite the fact that what comes after may sometimes be omitted if it is obvious.
Fun-fact
Although it is not a rule, ものだから will primarily be used when explaining one's actions, as a way of emphasizing that the situation of (A) specifically led to the speaker doing (B).
