Met an older woman over Christmas break while visiting home town.

First date let her know I was more interested in the idea of open relationships. Nothing has been discussed ever since regarding relationships or ‘what are we’

She’s been flying to my city every month to see me. Activities are usually lined up for the weekend with as much sex as I choose to initiate.

Question is: should I at one point or another clarify to her that I’m not looking for a relationship out of respect for her? Or should I just assume that it is what it is until she brings the ‘what are we’ conversation up? At which point I can clarify that I’m not looking for a relationship.
