I went through almost the same exact thing earlier this summer. This person pursued me after my long relationship ended. I wanted to be friends, but the person kissed me first, kept asking to hang out, etc. I'm not sure if you have ever heard of love-bombing, but it seems like that is the new "ghosting," and I think it feels worse. They make promises early on and make it seem like they are infatuated with you, then all of a sudden, they break it off or disappear. Anyway, we slept together, and I got emotional with guilt for falling for someone so fast after my relationship, and the new person basically bounced and blamed it on me for not being over my ex.

There is a lot more to this story, but essentially it was a form of manipulation which continued on in a few other instances. I still think about this person often even after realizing what I just mentioned and realizing this person was basically full of shit.

Time has helped me along with keeping busy. The cliché solutions. I gave up on dating for a bit, even went back to my ex to see if we could work things out, but ultimately, I think what will help the most is keep plugging along and meeting people to find someone best suited to you. Definitely don't beat yourself up about not using condoms. It happens. You did the right thing and got tested after.
