My girlfriend (27f) called me (29m) disrespectful for refusing to cancel celebratory drinks
With my job I’ve have had a lot of exams to complete over the last three years to become chartered. I started work with two other people, let’s call them Megan and David.
None of us live on the town where we work as we pretty much work from home most of the time but me and Megan live on the same town. We finished our final exam this spring and have all passed so Megan suggested we all go out for drinks to celebrate.
David said it sounds good but it would be hard for him to get to us as he doesn’t live near us so just said for me and Megan to go if we wanted. Megan and I spoke. and suggested inviting our partners along.
Megan's boyfriend messaged me to thank me for the invite but mentioned he was going away for work for a few weeks so just to meet up without him. When I invited my gf she said she doesn't want to go but that I shouldn't be going out for drinks with a woman on my own.
I pointed out we'll only be on our own because she's refusing to go so she doesn't get to stop me celebrating finally finishing exams. She just said I was being disrespectful and that I should be cancelling.
Does anyone have any advice on how bed to approach this or have any other views on it?
tl;dr i have plans to celebrate becoming chartered in my field. my girlfriend is invited but is refusing to go and is arguing I should cancel since I shouldn’t be going for drinks with another woman.
