I just blocked her "not my boyfriend"s number

I just called her. I told her

I wasn't going to allow her to use a phone I paid for to speak to him. She said who. I said your boy friend. She said he's not my boyfriend, I'm trying to get legal help from his cousin so you can unlock it. I told her I didn't care what the relationship was it was inappropriate and I wasn't paying for her to talk to him, that I was not going to unlock it. She said fine. I said fin and we hung up.

tension was thick

I feel stressed.
