From personal experience I think your daughter was hoping that you both may realise that you have missed each other and was giving you both a last chance to get back together.
Probably her Dad throwing another woman into the equation completely threw her and she doesn't want to take sides so didn't know how to say 'no'.
My advice for what it's worth, don't go, make any excuse and although it could be worse the next time you do have to meet your ex, at least you have saved your daughter and family from an excruciatingly embarrassing meal at the moment, when everyone is getting used to the new status quo.
