I was cycling three plates in my home country; I'm overseas for business currently for awhile.

One of them thinks we're an item despite me explicitly saying we're not exclusive and I was dating around (i.e fucking other women).

She was a virgin before me so she took the whole dynamic as something more, bought me gifts, tried to invite me to meet her folks despite the above discussion.

I need to reinforce we're not an item and end it whilst mitigating the damage.

Thoughts on best practice? Over the phone or simply a message.

I've done breakups before but I feel as if she will take it worse; she's a junior Doctor and most of the men she interacts with are older married men, and she has put me on a pedestal.
