first and foremost, you definitely shouldn’t stop talking about it, if that’s what you want to do. if something is on your mind and you want to express it, i feel like the harmful thing to do would be to bottle it up! just keep talking about it as much as you feel you need to and i can guarantee you that, over time, it’ll plague you less and less. eventually it’ll just become another aspect of your life you‘ve successfully grown and learned from!
my advice re: getting back out there is to simply take it slow. be observant for any red flags that you think could be indicative of a larger issue. also, make your core values clear from day 1! if someone really wants to be in your life, they’ll make it clear that they hold similar values :)
also, be sure to set your boundaries. be honest about your past and let them know that you’re still healing from it. any genuinely empathetic human being will internalize what you shared with them and be understanding!
overall, i’d urge you to remember that most people are not like your ex; most people want to cultivate healthy and loving relationships! i can’t imagine what you’ve had to endure - but thankfully you get to go out there and meet the person who deserves your love !! it’s super exciting !! woo!!!!
best of luck ☺️
