general friends, yes. Close friends..from my experience no.
I tried very very hard to accept my bf's 'friendship' with a girl at work, but it became too much.
I did not want to appear jealous and I initially got along with the girl very well. But after awhile (over a year) I did start to feel uncomfortable when she would text him up to 20 times a day, call him at 10:30pm and meet up with him for a catchup after work (they work at a restaurant) and then be talking till 2am.
What bothered me the MOST was that she was well aware that I was not comfortable with their closeness and continued to contact my bf more than ever. Whenever my bf said 'SBB is worried that I haven't come home yet' when I texted him at 1:30, she just goes 'oh! I'm so sorry! I didn't mean to cause you guys to fight!' but then she would still do it..It was like she KNEW what she was doing, but chose to ignore it and then pretend to be sorry/unknowing later. I never spoke to her about it because I thought it would be rude, and my bf would not be happy if I did. At the end of the day it's their friendship and I shouldn't interfere.
I spoke to him about how uncomfortable I was, and he just shrugged it off, saying 'she's like my little sister, that's all'.
One time I went out with the two of them, thinking, sure I'll try to get to know her better, give her a chance. But I am naturally a more quiet person, and not very chatty. It's certainly not like she made some great attempt to talk to me either. Later I find out she complained to my bf 'SBB hates me!'. I NEVER said such a thing, nor was I rude to her. My bf told me that I was rude by ignoring her. ?!? I was never anything short of polite to that girl, yes I do not radiate warmth, but I am never rude. I felt uncomfortable with their friendship and wary of her, but even at that point, I did not hate her.
After that, I find out she keeps messaging things like 'ohh I wanna watch this tv show, but it's too scary, I can't watch it alone!' 'I'd watch it with you, but I don't think my gf would like it' 'yea, I always knew your gf was crazy. she's going to try and kill me because she hates me so much!'..there are much more of these type of messages
Yes, I found out about those messages because after feeling uncomfortable for a month and eventually having a large fight with the bf, I broke a big relationship rule and looked at the phone. Months have passed and my heart still breaks when I think about it. There is no trust left, who would've thought after 6 years?
So no. Some friendships are just too close and if you have a partner, don't let them get hurt.
