My friend and I used to be close, but I don't know now. She's really negative and only engages in conversation if it relates to her. I want her to be like the way she was when we first met. What should I do?

Sit down with your friend and talk to them alone, explain how you feel. Talk about you, ask her for the advice on things and tell her how she’s been is affecting you, maybe she doesn’t realise and needs reminding your there too and need her aswell

Try calmly talking to her in a private area where no one will interrupt you. Talk to her about how you miss the way your relationship used to be and ask her why she is being so negative. If she gets mad stay calm and give her time to process what you told her.

Tell her you notice that she has changed. Something may be going on privately that you do not know about, and it might be good to ask gently about this. If there is nothing, simply explain how you feel and how you feel your relationship has changed. She may not even know this is going on, as Sarah said.

Talk to her about it. Talking can go a long way in solving your lost relationship. The probability that she is acting like that is may because of the pain that you may caused her, either willingly or unwillingly. As intense as you can get, talk and avoid blame games. Blame games usually cause more damage to a relationship. One should also be willing to repent even though you feel like you are the one on the right. If he/she has felt guilty, he/she will also repent. As you talk...ensure that you are as honest to her as possible about your feelings and admit that you miss his or her company. He/she may be missing your company too.

I'd suggest talking to her about it and explaining how you feel. Maybe she isn't even aware she's doing something wrong? Conflicts and unpleasant situations in relationships are often a result of misunderstandment and lack of communication.

When something like this happens within any relationship a useful approach to fixing this is by talking to the person about how this makes you feel. In response to you wanting her to be the way she was when you first met is almost impossible to ask of someone because things and people are always changing but, it important to find balance again between your friendship. It is never fair to have a friend that is one sided and makes things all about them. A friendship should be a shared input not just about one person. Let her know that you want her to care about you just as much as you care about her.
