Here's that question

I'm the yin to Carlos' yang .....
..
Nope it's not ok...You're either with me or against me on this but to me I'm either in your gang or I'm not...Him keeping a secret about a friend of mine, unless it was a surprise party for me, I don't see why he would cuz I wouldn't ...I realize he might be trying to keep her confidence but at what expense, ur feelings?....
..
In a relationship I believe each partner should be other's "go to" person, for the good, the bad and the ugly...Not to say they don't or can't have other confidants but little things like this can weaken links in the chain...It stays strong because you trust each other to protect, nourish the bond...
..
Not everyone is capable of doing it but good relationships involve being sensitive to vulnerabilities of the partners...I'd tell him exactly what u know, in a non-accusatory way, so he doesn't misinterpret it for "jealousy towards the other woman", that you're uncomfortable with him keeping her pregnancy a secret...The truth...Angie..

Even if you're in a relationship what's yours is yours and what's mine is mine can still work...You can share many things, but I think you can also have your own things...I don't think everything has to be shared between partners, including secrets...

You say that it makes you uncomfortable...That, to me, is enough to know...If you're uncomfortable with how close they are, your bf should do whatever it takes to make you feel better.....
..
The fact that he's lying about things is just another big red flag...I think you need to have a talk with him about this, and let him know that you feel like the relationship he has with her is staring to cross a few lines...Tell him you're glad they're friends, but that you feel like she's the most important female in his life...
..
He might say you're being insecure, and maybe you are just a little tiny bit, but it doesn't really matter...He's not giving you a reason to feel secure, and he needs to rectify that...

I don't all details of the situation but secrets between someone's boyfriend and the girlfriend's female friend are glorfied on tv but never work out well in real life...I have some first hand experience with this and my situation blew up... There are lots of needy people out there and sometimes they will use their problems (no matter how real they are) as a way of manipulating a way to get some closeness with someone (sometimes unconsciously)...I would suggest you spend some time your girlfriend and shift the relationship so that her closeness is with you and not with him on his own...Good Luck...

I agree with Raven, maybe the girl opened up to him at the right time and isn't ready to tell anyone else yet. I don't tell my boyfriend everything that is going on in my friends lives and I don't expect him to tell me either. I would hope that my friend wouldn't tell their husband absolutely everything I tell them, and the ones that do, I don't tell them everything anymore...Once I had told a friend something personal about my sex life and two weeks later I was getting advice on the subject from my other friend's husband who had been told by my original friend's husband. I mean HELLO?!..
