DP has an old female friend who he sees every month or two. They go regularly for meals with a couple, and as a foursome used to go on weekend breaks. The friend is married.
I've been with DP for a couple of years. I met this group once, and the friend said she felt like a third wheel when my DP was out of earshot. I found this strange as they are a very relaxed group. When I told DP he was shocked at her rudeness.
Anyway, that night she arranged her own lift home instead of sharing a taxi with my DP like she usually would. Since then, they have gone out several times and always taxi share like before.
Is it odd that I want to go out with them again but suggest we all share a taxi so she gets used to me being about?
