Strange day.....

Ever since our great Maui vacation, my wife and I have slowly moved back into our routine.  She being to busy and irritated that I want to hang out with her.  Maui was soooo fun with my little family.  But now that we're back in CA she's fallen back into a routine of being too busy to go on dates.  Too busy for the little things.  I have to say I love you first every time.  Back to the "I'm part of the furniture" life.
So I took her to breakfast this morning.  The kids still asleep at home.  I told her I wanted to talk about stuff.  She said go ahead.  So I started out by tell her how I felt.  That our routine is back.  And this time I want more.  She was so attracted to her OM that she said she would have (and did) had sex with him anyway he wanted.  But with me, nothing.  She agreed with me that she has an issue with me.  And she even said that a part of her doesn't like me.  So what do I do now?  I'm trying to stay with this relationship, but I feel so so so alone right now.
Maybe that's what I need to do; be alone right now for awhile.  I struggle with this kind of one-sided love in my marriage, but I've always thought that it would somehow be alright and what we had would return.  But this is scary.  
Okay, so what if my marriage doesn't work out?  What if my wife never gets any of those old feelings back?  Do I stay for our three kids?  For our families?  Ugh!!  Ugh!!!  Ugh!!!
 
I just want to roll up in a ball - alone.
