Do I think you should just let it go? Probably not, but there is zero point in obsessively checking for outbreaks. If you might have genital HSV 1, you may never have a recognized outbreak. And if you have oral HSV 1, you would notice it with a quick look in the mirror
I would have your future husband tested and if also positive for HSV 1, stop worrying about transmission. If he is negative and is concerned about acquiring HSV 1, you could take daily antiviral medication to try to reduced the risk of infecting him by giving him oral sex. he needs to be a big part of that decision.
