be prepared to face rejection and possibly lose him or her. Because if you're crazy about someone who was once just a best friend, you won't want to be in the friend-zone.

Very few of them were ok with a strict lover arrangement.

However, if it's really THAT strong of a connection, then it'll be reciprocated, which might make it all worth it. If you feel that it's not mutual, though, and you value having the person in your life by any means, don't act on it and wait it out — maybe it's just a temporary confusion.

Maybe you just have a strong emotional bond, but it doesn't mean that you're IN LOVE with the person.

Seeing as how you were probably highly intoxicated the first time around, you decide to see this person one more time.

This decision is most likely the result of you not being certain whether or not the person was good in bed. Now it is acceptable for you to text this person at odd hours, preferably when you're intoxicated or about to be intoxicated, to come over.
