does this sound like BPD to anyone?

Every time i start talking to someone romantically i start to revolve my life and mood around them.. i don’t want to do this anymore. I started talking to a new guy a couple weeks ago and we got into an argument recently not really even- just a disagreement and he ignored me for half of a day and said he was just busy in general and didn’t wanna talk about it anymore and wanted to leave it alone and take a “step back” i admit we were going a little too fast and seeing each-other everyday to the point of where it became too much.

The point is whenever we got into the argument and he didn’t talk to me i completely broke down, my moods always rely on my partners i start to become so invested in that person they are all i think about. I don’t want to live like this emotionally anymore and i want to be in a healthy relationship and separate my feelings of self worth and my partners mood or if we had a good “day” I’m starting to think i show very big signs of being bipolar.. i don’t want to live my life so upset and scared and anxious every time i start talking to a new guy. Any advice?
