Take this w/ a grain of salt because I am by
no means a relationship expert.
In fact, I think you gave me advice on something recently. Anyway, as someone who does this as well, don't beat yourself up about this- don't be "repulsed" by your past actions. You did the best you could at the time. Just don't look at it so negatively, that you're a bad person in any way. Be positive and focus on the possibilities that this new knowledge opens up. Good luck and give yourself the benefit of the doubt in your new relationship.
