lies but not really???? RANT,suggestions ?

Hey girls so me and my boyfriend have had a very tricky relationship because we have broken up twice because of my schedule being very hectic yet we are trying to make it work. I am not a controlling girlfriend and I let him go out with his friends whenever he wants. However the other night he went out to play basketball and at around 10:30 pm he texted me that he wa son his way home. He then proceeded to tell me that he wanted his friends to be my friends, and I said that it's ok since I know he doesn't like his boy friends benign around me yet he said those aren't the only friends he has that's when I said well not like you hang with non boy friends. The point is that his bestfriend (female) from high school was there with some girls and that although she stopped her friendship with him for her ex. Now she wants to be friends again and so does he. I am having a hard time with this because I feel like something is off and that maybe she has alterior motives. And since so many things have happened between him and me I'm scared that he will leave me. I am so confused that I just need advice im sorry for the rant 😓💖 it's just that ever since I talked to him about the situation he is holding back idk if it's because he wants to see how mad I can get or if there is something else ....
