Take your time to think things over.
If you can make your relationship work, that's great. I'd advise you to make sure it's what you both want.
I wouldn't necessarily take him at his word right now as you're right, actions do speak louder than words. It's pretty scummy of him to cheat on his pregnant wife, and I fear he may be saying he wants to stay together in order to save face. I mean people will look down on him for abandoning a pregnant wife, but if he waits for her to give birth and then says it's just not working, he saves major face and comes out looking like the noble man who stood by his woman------and despite his best efforts, it wasn't meant to be.
Of course I really do hope that things can work out, but I'd be wary of his words as there could be ulterior motives.
Make plans now and get as much support as you can in case of the worst case scenario. On one hand it may not be the best to tell your friends/family about this situation as if you stay with him, everyone will look down on your husband and it may make your marriage more difficult. More importantly, I think that you should be open with friends/family as you'll need support if you end up being a single parent of 2 young children. (And since their needs are of utmost importance, I'd say go with the latter option.)
