Why does my girlfriend hate me all of a sudden?

What gives you the impression that she hates you? I'm sure she doesn't! Is there anything she is going through that may be stressful for her? in most cases when under a lot of stress people tend to push away those closest to them. I suggest you sitting down with her and having a long , meaningful chat. Tell her how you feel and inform her you are there for her no matter what! I hope everything works out for you! :)

There's probably something she's had to deal with, and it's hard for her. Try talking to her about what happened and see what's been going on. She's most likely just stressed out about something.

There might be an unsolved issue between the two of you and it is eating at her. Try getting her to tell you what it is and solve it.

i dont think that it can be really sudden,you need to think well of what led you to this point,the only case that she is suddenly changed and you are pretty sure that you didnt do anything wrong is that if she is emotionally unstable and in this case maybe the break up is the most wise decision

She probably doesn't hate you. You just feel things have changed. If you're concerned, air your concerns without trying to argue

You can ask your girlfriend to talk, face to face is the best idea, you can try to explain that she gives you the feeling that she hates you, talk things out! pretty sure she doesn't hate you.

You can ask your girlfriend what's wrong with her and tell her how you feel, you can also try to think about any previous arguments you have had which could cause her to feel such a way towards you.

no one may never know unless you ask. She could just have a lot going on she just might need someone to lean on when times get rough

All the hate she has may not be directed at you: She could be dealing with issues with friends, family, school, work, etc. Since you are one of the people who spend the most time with her, you're more likely to feel the brunt of that anger. Take some time to ask what's going on and how she's feeling-- see how you can help take some stress off and if any of it is due to you.

Your girlfriend may hate you for a few reasons but one she probably doesn’t hate you she can be having a bad day or something in her personal life could have happened so show support and ask her what is going on. Think back and see if you can rember doing anything wrong that could have upset her and I’d you do ask her about it and apologize. If you can’t she may have lost feeling and that is something she must come to you to talk about face to face and give you the respect you deserve from your girlfriend
