Hoping for a bit of advice from the wise ladies on mumsnet. I'm seeing a guy and we are going on a fourth date later this week. He seems really keen and I like him so happy to see how things progress. A while a go I agreed to go on holiday with my FWB, he lives in another Country and we are meeting half way. We have both spent quite a bit of money organising it. We have lots of exciting things planned and I'm looking forward to it. I mentioned I was going on holiday with a friend and he has assumed it's female and says what a good time I will have etc. I don't know if I need to put him straight we haven't said we are exclusive and it's only the fourth time we will have met. Just for context if my FWB hadn't moved to the other side of the world we would likely be in a relationship. Do I need to tell him or wait until (or if) we have the exclusivity chat?
