On the last string

To start off I am 24 and my bf is 29. I love this man so much, but recently we have had one issue that seems to be putting a toll on our relationship. About a month ago he tells me that a girl that he used to talk to (only on the phone, due to the fact that she lives in Ohio) has gotten back in contact with him. I was glad that he shared this information with me. He said that she and her mom was coming to California and wanted to meet him. I said that was cool. So time passes and she arrives in San Francisco, and I find out that he hasn't told her that he has and lives with a girlfriend. I also have seen texts from her telling him that he shouldn't be nervous to meet her because she is there for him and that she loves him. I had asked if I could go with him to meet her, he told me that he didn't know. One weekend he told me that I should go visit my mom, I was ok with it, but then I found out that that is when he wanted to meet up with them. Then he starts getting mad at me because my mom was busy that weekend and my father was in the hospital going through dialysis. He said that I was just doing it on purpose, that I should trust him and I am being insecure. Now he wants me to move out because he says that I am up his butt the whole time. He says he wants to be able to go out whenever, with whomever he wants to, whether it includes me or not. What does all this mean? Is it just me and being insecure or am I just over analyzing it?

You are not over analyzing. This is a red flag going up and waving frantically in the air! It is clear from an outsider's prospective that he intended to meet this girl who he had not told about you under the assumption you did not exist as his girlfriend. This is no better than outright cheating. Anytime a man does not tell the other female that he is attached, it is emotional cheating. It is not only unfair and hurtful to you, but if the female is a good hearted person it is hurtful to her as well. She is pursuing a relationship with him not having the correct information. There has been a breech of trust and you will have to work very closely to ensure that you resolve this issue entirely before it happens again. I've been through this and it is hurtful but the Hirt only deepens when the trust breech is not resolved.
