Boyfriends best girl friend texts him alot!

Hello,

I am in a current situation where my boyfriends best friend who is a girl keeps texting him and I believe that is okay because I have guy friends that I text as well, but not every single day. Let's refer to her as "Brianna." I have met Brianna and we get along really well and I love her because she is the sweetest thing and we texted each other once in a while too, but she is texting my boyfriend everyday, and the twist here is that she is married. She will sometimes text him saying that she misses him and that's okay because one of my guy friends and I will say that, but we only see each other 1 time every 3 months because of distance and we only talk 1 time every 2 weeks.

What I am getting at is that Brianna sees my boyfriend or hangouts with us and her husband every 2 days and she still says that. It honestly never bothered me until the other day when she left for a vacation with her family and on the third day of departure she texted him saying "I miss you." My boyfriend told me and I was asking when she was back because I missed hanging around with Brianna and her husband as well. The following day she texted to same thing, but said it 3 times during the whole day to start a new conversation with him. One saying, "I'm bored and miss you."

In my defense I feel like it is okay to say I miss you to someone, but isn't there a limit to saying it? Especially if Brianna is currently on vacation with her husband and family. Shouldn't she be enjoying herself and not texting my boyfriend all the time?

I may be overthinking this, but I did speak to my boyfriend about it and he does agree that it is over the top and told me that he would not like it if my guy friends did the same. He also said he will talk to her about it, but I also told him that I don't want any conflict because I don't have anything against her...
My question is: what do you think? Am I overthinking this situation?

I personally feel like that is a little much. My bff is in California and I'm in FL we barely see each other, we do text everyday BUT I only tell him I miss him like maybe once a month. Maybe lol

Good for your bf for saying he'd talk to her about it. A lot of guys wouldn't do that. Sounds like you got yourself a good man!

I think you do have a problem with this whole situation or you wouldn't have written in the forum. I understand you are trying to act like the secure, cool GF, but obviously you are feeling threatened in some way. If you are truly friendly and ok with "Brianna", you should speak to her yourself. Don't make your boyfriend do it. Just tell her you are uncomfortable with the communication. See if she has any type of explanation for the constant texts.
