It may be best to very calmly tell him what you are planning to do - that if he hasn't booked the retreat AND broken it off with OW by the time he gets back from his trip, that you will serve him. Otherwise, if you say nothing to him now (eventhough you've already said it to him), especially after the nice weekend you had as a family, he may misinterpret that you are ok with the status quo, he'll continue to stall and he'll be very angry when you do serve him. This way the choice will be his.
One question - how will you know for sure that he's actually ended it with OW while he's away on his trip? I wouldn't take his word for it.
