Just wondering if i/ve only had 1 relationship but i think they had BPD.

It started off with insane idealization/infatuation with me. They made me feel amazing. Absolutely love bombed. Felt like i was the best thing ever. They would react extremely badly if i couldn't take them out. They cried when i told them i couldn't see them because i had to look after my parents. They were EXTREMELY clingy. Constant texts throughout the day and extreme anger if i didn't respond within 30 minutes. Seem to have extremely bad self esteem issues. Seemed highly impulsive e.g. had a history of high promiscuity. Seemed to lack empathy to people and liked animals more than people.  Do you think they had BPD?
