DP has a hobby which takes up a fair bit of time, I’m not really involved as it isn’t my thing however do go to a lot of the events with him mainly to drive him but they end up being a good laugh and generally have things that I volunteer in whilst I’m there.
Recently a new woman has joined the hobby, she is a friend of one of the other group members.
We were out for DP’s birthday last week and through the night this new woman was getting very close to DP, leaning against him at times and generally acting as if she has a crush on him, other people on our night out noticed but I ignored it.
In our last bar she was sat on the other side of DP and started to run her hand up his thigh, at that point DP jumped up and made excuses to go outside, I text him while he was outside just to confirm what I’d seen and he did, admitting she’d been trying to be close to him all night.
I’m not angry at DP at all, maybe he could’ve told her to stop earlier in the night (but he said that he had) but I’m furious with this new woman, my intuition throughout the night was telling me threat, she isn’t to our relationship but do I confront/discuss with her about what she did? DP feels that it was only because she was drunk she was acting like this but I’m not sure.
She will be at future hobby events so there is that to consider, any advice welcome
