But, this is how it’s supposed to be.
Your frustration, anger, outrage…etc should be directed at the person you’re in the relationship with, period.
A guy I dated in high school cheated on me with someone who has now been one of my best friends for 10 years.
She sends me photos of her family, we send cards for birthdays…etc.
She’s one of the best people I’ve ever met.
I should add, even if the person your partner cheated on you with knew of your existence, you still should only be upset with the person you were dating. Here’s why: you created a relationship based on specific guidelines, personal needs/wants, goals…etc with THAT person, not with the person your partner cheated on.
I try explaining this shit to dude (males) all the time. No one gets this shit.
