Why can’t others be this way?

I will start off with my good news. I got my letter through for my ultrasound appointment today. I have to go for it next month. I thought that I would have to wait longer than that given what the GP told me on the phone last month.

Now, on to todays topic. I have noticed how uncommitted people can be. Some people will flirt (they could say be friendly) to multiple people at once. Those of you who know me are aware that 6 months ago someone I liked stopped talking to me due to me trying to help them by getting too involved in something. That is beside the point here. I was loyal because I liked them. We weren’t exclusive but I wasn’t giving others attention at the same time. I later discovered that while we were talking they were being friendly with several others in a flirty tone. I don’t know if there is something wrong with me. I simply can’t be that way. I wasn’t looking for someone when they came along but still ended up feeling heartbroken after they decided that they didn’t want to talk to me ever again. Why am I so upset over what I was like whatever about when we met each other on TikTok? It makes no sense.
