<human>: Can you succinctly summarize the text in 1-3 sentences?

This may be a petty thing to ask, but this is my first relationship, so I'm not sure how things typically go in regards to exes. My boyfriend and I were talking and his ex, Jill, was mentioned. He had told me months ago that he told Jill that he didn't want to be in contact with her.

Tonight, i asked if she has contacting him at all, and he told me that she has a couple times. He said it was mainly just her catching up with him, and that they were just short conversations. I asked if he initiated any of them. He said no. However, he mentioned that she wanted to meet up for coffee once school starts back up. He asked me if I was comfortable with that. I wasn't really that comfortable with it, but I don't want to seem insecure and untrusting of him.

Do I have a right to be uncomfortable with him wanting to meet up with his ex? My main problem with this situation is that he didn't tell me that she had contacted him when she did, and he did not tell me that he was planning on meeting up with his ex for coffee. Do I have the right to be upset about that? Should I tell him any of these thoughts or just let it slide?
<bot>: boyfriend's ex contacted him a few times, he didn't tell me about the messages or that they planned on meeting for coffee; should i be annoyed/ upset?
