Mitch and Blanche are an example of a co-dependent relationship that is founded on mutual loneliness and the desire to be with someone – anyone – to distract themselves from previously suffered emotional damage. The only reason these two are together at all is out of mutual need. Or, as Mitch says, “You need somebody. And I need somebody, too. Could it be — you and me, Blanche?” (6.121).
Mitch might have his own reasons for liking Blanche, but we have a hard time believing that she harbors any real feelings for him. When they meet, it’s clear that she has to carry the conversation entirely herself. Mitch is a bit slow, definitely awkward, and way inexperienced with women. This is in part why it’s so easy for Blanche to manipulate him.
The big tip-off as to Blanche’s real motives comes when Stella asks her, “Do you want him?” and she replies, “I want to rest! I want to breathe quietly again! Yes—I want Mitch…very badly! Just think! If it happens! I can leave here and not be anyone’s problem…” (5.86-7). It’s more about what Mitch can do for her than who Mitch actually is. And it’s more about being married at all than it is about having him in particular as a husband.
