Do I have valid reason to feel like this? Should boys have girl best friends?

i have many female besties yet i share no attraction towards them its practically just like having a male best friend but they are female i guess lol, although your boyfriend does sound like a bit of a **** ngl.

my boy best friend had a girlfriend who disliked me because she thought that he liked me. i wasn't even flirting with him or anything, I would just talk to him on a daily basis. maybe it's a similar situation??

So my boyfriend is friends with a girl who he used to like for years. Me and my boyfriend have been together for a year now. When we first got together one of his friends said to me that I would never compare to her and to this day his friends still say to me how in love he was with her to me. He also always used to talk about her and praised her and we went through a stage where he would just keep talking about her and it made me feel really ****. There has also been a time Ives been sitting next to him and he's facetime her to come to a party and he said to her in front of me it was boring and would be better if she was there. She is the main cause of arguments. I am a very insecure person so I think that adds to it. The first time I met her she was very rude to me and since then she has always been rude to not just me but my friends too when we see each other. One of my boyfriends friends also told me she doesn't like it when her friends get girlfriends along with some other girls in the group. I sometimes feel uncomfortable with my boyfriend around her. I fully trust him and I have tried to get over the feeling of uncomfortableness and be nice to her to see if she will be nice back but she never is. I found out today that he didn't just like her but they had a little something and she liked him too. I was always told he had just liked her and nothing else. He also told her mum how in love with her he was. I also found some messages when we was on his phone making jokes when we was together asking to go hotel and things. I feel if she was nicer to me it might not be much of a problem There has been one occasion where she has been nice and we was drunk. Am I just being insecure with this uncomfortable feeling? Do I have valid reasons to feel the way I feel? Do you think my boyfriend should still speak to her? Should boys have girl best friends if they have a girlfriend.
