Welcome and congratulations on your new relationship!
It sounds like you two are falling in love, so I don't think you don't have a thing to worry about
. You'll know when the time is right to share your story with him.
I've told lots of people about
my ostomy over the years and have never been rejected. Sorry to say this, but your ex's reaction was immature, self-centered, and definitely not normal. You deserve to be loved just the way you are.
Please keep us posted on how things go, and have a blast camping!
