Is dating gonna be like this now?

So I got diagnosed a couple months back and pretty much lost my relationship and potentially access to my daughter when I disclosed. I’m coming to terms with but I wanted to talk to some people that where actually going through the same thing. So I got on the Positive Singles app for the community stuff. Ended up meeting someone that works with me on there and really started vibing. We have ALOT in common. So I’m thinking cool…. Might be a good person to try to maybe connect with. We work together so when we found that out we went on a couple lunch dates for a week or two. Then we went on a date on our off day and eventually had sex that night. Super unplanned. We spoke for a couple days and planned another date for the weekend and she just went ghost on me. No reason no explanation no indication or anything. I work with this person so I can always go see her and ask but that’s just unprofessional in my opinion so I don’t even address it at work. It’s been bothering for me days tho and prior to being diagnosed I wouldn’t had even cared about something like this. I feel like this whole diagnosis is just making me overthink my relationships with people, especially since this is the first person I’ve been with sexually since finding out about it. I just needed to vent about this for real but am I tripping?
