Am I a bad person?

I have a guy best friend well had. We've been firends since high school and we got closer because my firend moved away. I find it very hard to get close to anyone because it's hard for me to trust. It took me a while to get comfortable being a close friend. A couple years ago my mom got diagnosed with Alzheimer's it's been very very difficult trying to be there to help my mom out but most of my time is taken up worrying about her. Me and my firend argued a lot because he would try to guide me to start new things which made me anxious and hanging out away from home made me worry more about my mom because she was at home and I was out doing something. He feels that we have a one sided firendship, and he thinks all these years I've used him to be my firend because my other friend moved away. We were firends before my other Best friend moved away. We argue a lot because he does things that get on my nerves so I bring it up and it continues he gets made at me that I asked him not to be flirty with me. He now doesn't want to be my firend because we've had issues in the past and he things that, I don't priorities our firendship but I've just been caught up in life. And he doesn't understand that i am trying to help look after my mom so I'm busy he thinks because I don't hang out that i don't like him. Now doesn't want me in his life. Am I a bad person?

For being to busy for my firends

He was there when I needed help but I was to busy with my mom to focus on what he must have been going through.
