**Slight rant**
I forgot to say that she's only 18, if that changes anything.
My best friend (the girl who is supposed to be my MOH) has been with her BF for five months, and granted they seem to be very much in love, she is convinced that she is going to spend forever with him and they will be moving in together and getting married. She's talking about when her and her BF will get married, how soon it may be, etc.
I'm not sure how to tell her she needs to cool it on the wedding planning or she's going to drive herself crazy. That and I'm really nervous they'll get engaged before me and my BF do. I know, that probably sounds selfish but I've been her friend for 8 years and I know how she is and this is something that will pass if they break up.
I'm just not sure what to do.... she has the tendency to blow of me and her other friends for her boyfriend and also hangs out with this not-so-nice girl who I know is talking bad about me.
Sorry if this is all over the place.
Edit:
Thanks for the eye opener you guys. I'm just a mess of emotion about her and how our relationship has changed. As for the MOH comment, I see now it may have been a mistake to make such a serious promise especially since our relationship has changed very much since high school when the promise was made, but I'll definitely have to cross that bridge when the time comes.As for Goldlie said, it does sound very selfish about what I said about her possibly getting engaged before I do. This is the kind of advice I needed as opposed to someone just holding my hand and telling me what I want to hear.
