Fifty and (un)Fabulous!

How frustrating this is..... I don't know how W and I went this long being in a happy marriage, and now everytime we talk about F, he gets mad at me. It confounds me. I went to talk with Sally, my therapist, today. It's my 2nd time with her.  I have been learning how my actions have affected my relationship with F. I guess some things may be perfectly clear to W, but they are revelations to me. So tonight when he asked how it went with S, I began to tell him, and he jumped on my comments and gave his opinions on top of mine, and there was no point even talking about it, because it was clear he didn't agree with me. I felt as though I was cut off at the pass.  It was infuriating!  I told him I just couldn't explain it to him if he jumped in like that. He kept saying he didn't understand. I dropped it and said we would talk at another time.
Then he was asking me if I spoke to F about his 5th class he was supposed to sign up for. I said no. He wanted to know why not. So after dinner, I rang up F.  I asked him about the course, and explained how the circumstances surrounding his lack of a 5th course will end up creating consequences for him. He seemed to understand. On the course sheet from school, it says at the bottom that tuition is due on 8/4/2010 (today.)  I told him 2 weeks ago that we'd need to know the $ addition of the 5th course in order to pay tuition on time. So I told him tonight that it was due today and we need to know. When I got off the phone with F, Warren jumped all over me. He said tuition isn't due today, and why did I tell F that! (Umm.... because it says so one the course sheet, you asshole!)  W said "But that's not true!" (He felt it wasn't because we never received a bill from the school.)  "Why would you tell him something that wasn't true?" ... like I purposely lied to F.  Grrrrrrrr!  Ridiculous. He's such a fuck sometimes.
