MM, what do you want to do for just yourself and your daughters?
Leave him, her, the sitch out of it. What would you do if you were single and he was not at the house?
Leave the possibility of any reaction/effect of your actions out of it - ie: If I drove home he'll ask me questions and I'll be very brief and this will cause him to become curious and maybe even jealous... you have to take him out of the equation.
What do YOU want to do? That's the only way you'll know you are making the right decision. It's the only non-variable in the whole mix - what YOU want to do.
Adding anything into it adds variables you have no control over which then creates a situation where you're trying to analyze all these possible effects and consequences and second guessing yourself.
When you decide for your desire and wants then you can be assured you did the right thing at the time you made the decision.
Edit: Read Dagny's post after I submitted this one. We're both saying the same thing. Serendipity baby.
