What do these "gave in to" and "relaxed into" mean?
ex)...Sitting near the end of a long, empty couch, she began to write...Marion scooted away, angry at the invasion of her space. The woman scoote closer, pushing up against her : "Every time I moved, she moved, until we ended up at the other end of the couch."...
They shared no common language, so they sat in silence. Marion gave in to the broad warm arm, the presence of the other, and relaxed into her.
"Give in" is a phrasal verb that means surrender or stop resisting.
"Relaxing into" something is trying to express that she stopped being tense and resistant to the other woman's proximity, and allowed herself to relax.
