Search Results: boyfriend flirt with my girl friends

First off my boyfriend is not the type to flirt or mess on with other girls and my best mate isn't either. However it's been a couple of months after me and my boyfriend got together that my best mate has been interested in what we do as a couple. Which obviously isn't a bad thing but the thing is whatever she tells or asks me comes off in a way that she doesn't want me and my boyfriend to continue our relationship.
At first she would tell me what a 'terrible gf' I am because I would apparently not 'spend enough time with him' and that I should 'make more of an effort with him'. So I take this advice and start spending more time with him however today she tells me that I am 'too clingy', that 'he is bound to break up with me', and that 'he's not interested' in me. Straight after telling me he wasn't interested in me she then went on to say that she was going to message my boyfriend for some weird reason because her and my boyfriend are 'really close friends' which is ridiculous because he barely talks to her.
Also whenever she asks about what dates we go on she always tells me that 'it's cringe' and has also told me before that I have changed to become 'sensitive' since dating my boyfriend and that it is a negative effect on me?
I don't understand her logic but just want to know some opinions based on this? She has though before herself told me that someone had asked her whether she had a crush on my boyfriend and that she went no and wouldn't do that to me.
