Change is the only constant in life

Corey update:
 In every relationship/affair, there comes a point where the pattern of communication changes, sometimes for the worse, sometimes for the better.  Corey calls me almost everyday, texts me a million times a day, but since almost getting caught, it has definitely changed.  I hate sounding paranoid, especially since Corey owes nothing to me and everything to his wife.  His wife stopped talking to him about the issue, even though we are both sure she knows exactly what is going on and is just not going to say anything more because a) she cheated first and b) they have to stay together for their daughter.

This is the first time it is happened.  Corey said he would call me yesterday morning and he didn't.  He ended up calling later (after I called him) and said he totally forgot bc his secretary called in sick and he got stuck with a bunch of stuff to do.  He didn't call me today either.  I texted him a little while ago, and while he answers, he seems a little distant and not as talkative as he usually is.

So am I being paranoid or just an attention whore?  I don't want to make a big deal if it's nothing and I don't want to mess up a good thing.  I always worry when a guy pays a lot of attention to me in the beginning and then it seems to fade.  It's like I want to keep making sure he is still into me.  I hate feeling like this, but I am afraid at any moment Corey can change his mind about seeing me in order to save his marriage.  My situation hasn't changed at all, so I am the one left alone in the end.  It feels like we are getting farther apart while we should be closer...

Ryan update:
I didn't know who else to talk to (I am a single girl and I don't know a lot of married people who are having affairs) so I told Ryan the drama with Corey and almost getting caught.  He thinks Corey may like me too much--which is not a bad thing.  Ryan would never put his marriage at so much risk.  At the first sign, he would stop talking to me and start trying to be faithful to his wife.  But he told me not to believe everything Corey says, which I don't, since I cannot except someone who is lying to his wife to always be honest with me.  But lying is another topic....

Ryan and I have been looking into sex clubs and swingers club.  Not sure if I wanna swap or even do a 3some, but I really wanna watch and be watched.  He found an online directory-type site and made an account.  I went on it yesterday and looked through some of the profiles.  There is some potential there, I think, so I am feeling a lil bit excited :)
