Shut the fuck up about the woes with your ex. You’re meant to move on and seek new people. Your ex should be old news, out of sight and out of mind. No new potential date should have to hear you crying about your bad marriage, about how things were once good between you and the other person. Because that’s you not letting go, regardless of what you’ve been through.
And if you keep droning on about your past relationships, you are chopping down what interest there is between you and the new person. That’s why you don’t get anyone new.
Something I don’t really like seeing when someone asks a question like this, is everyone just jerking someone around with their recommendations.
I would advise first to feel your tastes out, what do you feel like doing? What do you think is worth your time and even money to invest in? Whatever you feel gravitates you, go for it.
