家だとつい癖で - if it's at home, unconscious habit (cause?) ....

男やもめだとつい簡単に済ませてしまいがちで - i find it hard to use ~だと as a quote for ~ nor the "if
~ is the case usage" for this sentence.

Thank you.




The pattern **XだとY** can simply be thought of as " **if** (or " **when** ", or
" **as** ") X, **then** Y."

> **Example:** 家だと酔う ＝ if/when I'm home, (then) I'm drunk (or "I get drunk").

**つい** is, as you noted, a phrase indicating carelessness or unconscious
action, done (or left undone) by accident.

> **Example:** 家だとつい酔う ＝ if/when I'm home, (then) I unintentionally end up
> getting drunk.

so the first example of these two phrases together, **家だとつい癖で**
(『ちゃん』って言ってしまう)means as you thought

> "when I'm home, (I just say "chan") by habit"

**thanks to Naruto for pointing out the unspoken verb phrase, which means that
癖 is not being used as a simple noun as in "it's a habit", but is being used
adverbially as 癖で "by habit"**

... or more naturally in English "At home, it just comes out/slips out."

the second phrase in which this pairing is used, **男やもめだとつい簡単に済ませてしまいがち** ,
the **だと** uses the " **as** " meaning, since being a widower is not a
temporary state:

> "As a widower, I unintentionally have a tendency to get it over with
> simply."

("it" being eating or making something to eat, in this context)

a more natural English phrase might be "As a widower I tend to eat simply,
without thinking about it."
