Going from One to the Other

So I wrote about this subject back in January, and have a few more thoughts on the subject. As I was re-reading the "rules" I have to think to myself about feelings not getting involved. Hypothetical situation here, if two people have been "hooking up" for some time now and words are being said here and there that indicate feelings for one another, when does this no longer become "hooking up", "booty call", or whatever it is? One person tries to bring the conversation up, the other avoids, yet it is the other who is showing signs of jealousy and signs that they care more that what it is. The other person cares as well. But this is a situation where things become "hazy".
Do you end things, before emotions become more than what they are now, if one person won't have the conversation, even though it's apparent that they care. I think I may have answered the question myself. Of course you do. Why stay in a situation (although both have feelings for one another) where one cannot talk about the relationship. It's almost heartbreaking to put a person in a situation like that, it's a set up for destruction for both persons, and their hearts. But what do you do, stay there, and wait to see what happens? I think you have to move forward. Wow, life sure is full of complications, getting though them keeps you up, gives you a headache, and makes you wonder what you would do if you didn't have your friends :)
