Choco, drink and history aside, when the two of you were together in a non platonic way, did it feel comfortable and "right"?
Suspect you're both going to be wary and cautious with each other now as you've crossed the bedroom line and it's new territory but keep the spark and affection with him, don't withdraw but no need to get too heavy and ask him to start picking curtains with you.
Good first text. If he's feeling confused, that's normal, you're feeling it too by the sounds of it but don't withdraw or read too much into his acts or ommissions. Keep things positive and light while you both process what's going on. You're further ahead than him post marriage breakdown. If he's wavering don't take it to heart. I wavered with my friend now husband and thankfully for the both of us he had the conviction to be there for me no matter what, even after I told him I just wanted us to be friends.
You've got the kind of relationship where you can be straight with each other eg is this a date type discussion.
Life's complicated for both of you at the moment and whatever will be will be but in the meantime, you can still aim to be ports for each other while you deal with all the challenges in your life and agree that you're not looking to soul search and get all the answers straight away but keep on being there for each other in a fun, positive way and just see how things unfold without expectation and pressure to immediately blend on basis of history.
You have to start afresh with each other, your relationship has shifted and no matter what, will not be the same again.
It might end up being completely brilliant, a disaster or something a bit grey and an anti climax. Too early to tell and whatever the outcome, it shouldn't be something you regret, you both had to cross the line, it was brewing.
And like any good soap, there has to be a cliffhanger. So we're all waiting with you to find out how Totty replies to your text!
