You’re entitled to your opinion, but I respectfully disagree.
I’ve had several boyfriends/crushes and felt very similar while I was dating/hanging around all of them - which I think is the same case with OP. Most people don’t talk about their relationships like we are in this thread, either - they tend to have more issues with fair compromise and being treated well. Not lack of emotional connection on their part that they don’t understand. If there really wasn’t anything wrong, which isn’t my opinion, we would have been able to properly settle for at least one person by now, instead of always having a foot out of the door, or feeling something extreme when there’s nothing wrong.
