<human>: So my bf and I have been together for a year now, and he had been involved in a pretty serious relationship for 3 years that ended super messily maybe 2 years before we met. They were best friends and he won't give me any information about what happened. I found out he was meeting up with her when she had come to town, and I called him out on it. I found out he had not told her that we had been together for a year, and she doesn't even know I exist. I told him that it makes me very uncomfortable that he hasn't told her despite them being "friends", and he said they just don't talk about that type of stuff. He says that he's trying to fix their friendship and that's it, but I'm having trouble trusting him. What boundaries are okay for me to set? Am I being unreasonably jealous/suspicious/insane?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: BF won't tell his ex that we have been dating. He is trying to patch up their friendship, but the entire situation makes me incredibly uncomfortable and insecure in our relationship.
