Is it normal to recently feel the urge to be mean to my gf

Then you need to cut ties and end the relationship. You worry about hurting her by breaking up but the way you treat her is much worse. If you have those negative feelings you obviously are no longer in love so you need to end it so she can find someone who deservers her instead of treating her like shit.

I don't know what it is..now whenever I talk to her I get angry!! I feel bad after but I can't help it!

Its okay, she's probably a fatty. There's plenty of people out there that enjoy the likes of a female's FAT ASS. Take blacks or Hispanics for instance.

You have some commitment issues so you are try to push her away so you won't get hurt. So either let her into your life, or break up with the whole it's-not-you-it's-me bit because you are only hurting her.

It's 4 months...not a big loss. If you're doing this so early on, it won't get better. Don't be such a pussy and dump her.

She deserves better, end it and let her find someone who respects her

Break up with her. It will become an incredibly painful relationship if you don't.

break up now. it'll hurt both of you less in the long run. tell her straight up you're not interested anymore.

Break it off. You're wasting her time and your own. If it's this bad at four months think about the future. Move on, it's not fair to her

haha. dude you're kind of a douche at heart. but you're kind of nice. become a Buddhist.

Grow balls n break up damnit

4 months. That's all. Pfffttt. This your longest relationship ever or your first.

Do her the favor of ending it so that she can move on in her life and maybe pursue a guy who loves herback.it's actually cruel to keep leading her on just to not hurt her feelings.

Your view is a bit harsh but you do have a good point.

That's mean
