Am I being paranoid

Sorry it's kinda long.am just too emotional and confused.My boyfriend and I have dated for almost 4 years now and it hasn't all been smooth we have had our rough patches and we came through. ....but recently I have noticed that he is so close with his countrymate. ...Well I was in another city for 4 months and this girl is new.she came around that time I was living in another city due to internship...so during this time she used to cook alot and call my boyfriend over and vice versa. Sometimes I used to call my boyfriend late at night cz that's the only time I was free and almost every time they were together either eating or talking. When I came back the situation changed they stopped hanging out alot and stuff. .Then recently school opened and I went back to my school about 30minutes from their school. .I am graduating later this year so I can't stay at his place plus am a bit busy we only see each other on weekends....What bugs me most is they hang out everyday even when I'm there she still comes around and doesn't seem to have a hurry leaving. She really goes out of the way to prepare really good food for my man and calls him almost every day. ..There was a day in was on phone with my bayb and she called and my bayb wanted to disconnect our call just to tell her to bring food so they can eat together. Another time he asked me why I can't put a hairstyle she had once on my head bcz apparently he likes it. ..I have told him that I'm not comfortable with the amount of time they spend together and he keeps telling me that they are just countrymates and that I should be sure of my position in his life. ...That my problem is that I freak out whenever he is close to any girl n I don't trust that he can just be friends with his countrymate. ..He told me that I don't have that aura or the feeling to say that I'm his Queen....n his girlfriend. I don't know if I'm being paranoid or what but I really have a feeling deep down that he has feelings for her given the amount of time they spend together and all. ..Am I just being paranoid or there is something between them?
