Taking a Break

My friend recently told me that my boyfriend was being too nice to her and she felt that he was treating her like they were dating (They work together). Nothing sexual or weird, just offering to give her rides and things. It made her so anxious and worried for me and my relationship that she was overthinking it a lot and calling me very upset that I would ever believe him over her. We talked it over and I know that he's just a nice person and can be taken that way a lot. He's always been very loving and I've never had issues with him flirting or cheating. I told him I wanted to take a break to think about how I felt but I'm very confused because I've known him for much longer and we've been dating for 6 years. I'm staying with the friend for a period of time but I don't know if taking a break is the right thing to do. I really don't want to lose my friend or my boyfriend, but I hate to be away from him. She seems to think that I'll be staying with her for a while, like I have no intention to go back to him at all. She's gone through a lot of work to set up a room for me to stay and I'm really scared. I want to go back to my home with the person I love, my dog and my cat but she'll likely never talk to me again. It feels like I'm ruining my relationship for her and not for myself but I know she means well for me.
