Certainly not. If you attempt it, you will undoubtedly damage a relationship. However, when relationships evolve and people spend more time together, it is usual for them to tell one other "their day" and chat about practically everything, including decisions and the reasoning behind them. This isn't always a bad thing - hearing her side of things can help you understand why she did what she did and allow you to come to your own conclusions.
The best way to approach this subject is by asking open-ended questions. For example, you could say something like, "So, what brought this on?" or "Why did you decide to break up with him?" The more you know about your girlfriend's mind set, the better you will be able to advise/support her through difficult times.
In short, yes, she should tell you everything! Sharing and communicating are essential in any relationship, but they especially are important in long-term relationships where there is more to talk about and less time between conversations.
While there are some things you don't have to tell your spouse, it's a bit different when it comes to what you really must communicate. Although people may disagree on what they believe they must tell their spouse and what may be kept a secret, I believe some things are self-evident. For example: if something bad has happened or is about to happen, it should be told in time to prevent worse problems later. Also, if you think your spouse might try to hurt himself or herself, then you should tell someone about it.
There are two main reasons why you should always tell your partner everything: for his/her own good and because it makes life easier. If you keep something from your spouse, you are lying to him/her. This doesn't mean that you should tell your spouse every detail of your life, but he/she has a right to know anything that may affect him/her. Additionally, by being honest and open, you will create a closer bond with your partner. It is important to remember that while you do not have to tell your spouse everything, he/she does not want to be lied to either.
In conclusion, yes, you do have to tell your partner everything.
Telling your girlfriend she speaks too much may come out as disrespectful, so inform her in a gentler manner. You might tell her that it would make you extremely pleased if she would listen to what you have to say every few phrases. If she agrees, encourage her to be interested in your life and to ask questions. This will help her learn more about you and better understand your feelings.
The conversation should not be limited to one topic for very long. Add some variety by talking about subjects that interest both of you. Avoid politics or religion, but otherwise, go ahead and talk about anything that comes to mind.
If there is something that bothers you about her behavior, then tell her directly. Don't worry about hurting her feelings or appearing angry. Just state your concern honestly and give her a chance to explain herself. Maybe she just wants to share everything that's going on in her mind or maybe she has no idea why she gets on your nerves so much. Either way, listening well will show that you are an honest person who trusts her enough to speak up when you need to. This will make her feel valued and loved.
Remember, don't take things too seriously. She isn't trying to offend you! Have fun with it!
If you have "the conversation" with your girlfriend, she is unlikely to reveal what is truly upsetting her about the relationship. She may tell you that she's sad you're not interested in other women or that you need to be more romantic, but this likely isn't what is really bothering her.
The truth is, there are many things that may be upsetting your girlfriend that she cannot or will not tell you. Maybe she feels like she can't trust you, that you'll leave as soon as you get the chance. Or maybe she has a secret she doesn't want to share with anyone else. Whatever the case may be, it's important to ask her directly what is wrong for her so that you can help her feel better about the situation.
Remember, girls can be pretty tough if they want to be. If your girlfriend doesn't think you're going to stick around once she tells you what's wrong, then you shouldn't worry about her feelings too much. It's important that she knows you care enough to want to hear what's wrong so that you can fix it.
