In another post, I mentioned how there was a lot of dichotomy between Natalie and Ryan, from their male/female, novice/veteran, approaches, etc., there's a lot of contrasts which defines them.
I think, to some extent, the other minor characters represent extensions of the main characters. Julie could very well be Natalie in the years to come, settling down and getting married. Thematically that gives Ryan two different examples of dealing with the same theme outside of his own perspective.
Jim sort of serves as the instigator to Ryan's change - the spark, so to speak, because Ryan is forced to finally consider the situation from another point of view that is closer to his own (that being a middle-aged male).
Alex is an interesting case in terms of function in the overall story. Ryan's definitely attracted to her and they have a lot in common - but to me, she's almost a negative reflection of Ryan himself.
They're definitely not on the same page when "the scene" comes, but it's as if Ryan is once again forced to confront another possible perspective other than his own and it's a tough realization to swallow.
Her words "this is our escape" causes a shift in his perspective which had already been gradually changing: if he loved his economical lifestyle on the road so much, why was he escaping it? Was that even what he saw it as?
Perhaps at first, before realizing how empty his bag truly was. Alex then became the means for which he tried to fill that particular void in his life and it didn't work - she's got her own baggage, so to speak, that she prefers to leave at home altogether and in that sense, she appears to actually be practicing what he's been preaching.
