Sharing Our Innermost Thoughts

I came out of a relationship 3 hours ago. This relationship lasted for almost 5 years. He is a very kind and caring person. I felt safe with him. He’s also my first love. We are also engaged but my parents urged him to marry soon. Two months back he started to be distant and irritated because of that. We have been in a long distance relationship from the start and I’m an introvert girl. He’s a hyperactive and distracted guy. He always took me for granted. So it affected me deeply. But after the two months after he started to become distant, it became unbearable. He wanted me to study cat and get good package. Even though I don’t have interest in it, I agreed for him. Even after that we were still talking like strangers. It hurt me so much. My parents saw me cry twice over him. I told him how I felt numerous times but he just snapped at me each time. I wanted this relationship to work so much. Today again I pleaded and begged him to talk normally but he just said to concentrate in cat. I felt that he would start talking to me normally only after clearing cat. I wondered if I want a love like that. I tried many times to break up with him but I still go back to him each time. So 3 hrs ago, I told him I’m breaking up with him and this time I’m trying to be strong in my decision. Is my decision correct or am I just overthinking it?
