Hi TUMIgirl,
I understand how you feel but it should get better in time. It's best to keep it peaceful like this, since you share a child together. I also use the famous example Demi Moore and Bruce Willis who have remained good friends even though both are re-married. I'm also in a similar position except we are still living, not sleeping together for financial reasons - it's a long story. Luckily we're not at each others throat and are civil. To keep my sanity, I look at it, as we're in the 'business of raising children together" - I still care for him as the father of my children therefore I can still be pleasant. You still love him, but how about you love him as a friend and not as a husband. I know you're probably not there yet since I've had 3 1/2yrs to work mine out mentally. I agree with Pomegranate that counselling would help you deal with your feelings. I applaud you both for reamaining civil and your daughter will be the real winner in this. This will also save you both years of bitter resentment that many exes carry around for lifetimes.
