Not surprising you are not detached it takes a really long time and just comes naturally. You can speed up the process by avoiding those situations. If I had a nickel for every LBS who did the dinner thing and thought things were like normal I would have retired by now. The good news she doesn’t feel pressure from you. The bad news is you are slotted yourself into the friend zone. Your response should have been “can’t have plans gotta run”.
Prepare for the fact that there is another man in the picture that she panty upgraded for and right now you are a slot filler when she has free time. You need to decide if you are ok with that role.
