Scariest Part of a Relationship?

The scariest part for me would be, if the things we like together were just a lie, to get closer to each other and it turnes out we dont share the same interests. I wouldnt know what to do, while in other situatuons like betrayal, you can turn them down, but what do you do in such a situation? Turn the person down aswell?

Hmm I'd say it's everything that leads up to the breakup, you know when it's coming. Rather it be growing apart or something else, It's seems like it's always the same talks/conversations.

Being in one. Because at the start, they can give you false signals as to who they are. Then once you're in it, you can become "property". I speak from experience.
