Gestation period of horses is a bit over 11 months, so when you said you were in your 10th month... never mind. It's a bad joke. I don't think you're cheesy for showing affection.
If he doesn't get stressed by a conversation about getting back together or past events this coming week, then I think it's ok to bring him the peace offer. But he has to be the one who initiates the rekindling. He made that clear. Show you care for him, but don't talk about getting back yet.
A word about jalousy: I understand your feelings. And I don't know about the situations that made you upset. Maybe you had your reasons. But look at it from his perspective. If you have no real grounds to suspect him of cheating, acting jalously can be quite insulting. It can be cute when you pout a bit about it. But it is definitely annoying to get up in his face when he didn't do anything wrong. Keep that in mind next time you feel a bit jalous.
