Maybe you need to find your mom some friends

is your mothers name, by any chance, Yuno?

Sorry op, but I think your mom is jealous and she's a bitch for doing that to your girl friend.

Or she tried to run them off so she could have the cake to herself?

Because moms love getting told they are being irrational. I'm sure aster there talk OPs mom will suddenly come to her senses and thank OP for pointing it out.

Clearly #2 has never dealt with crazy.

I disagree with number 2. Why would you want to invite your mom after she yelled at your girlfriend like that. Also, like with children, you shouldn't reward that type of behavior. I'd just call the girlfriend and plan to meet up at another time or day.

I think the term "peacefully" is different from OP's mom's version.

Maybe his mom wouldn't let him. Or maybe he would feel bad about taking sides. It's hard to pick between your mother and your girlfriend, regardless of who's being irrational. It would be better for him to stick up for his girlfriend because his mother is in the wrong, but you don't know what his mom might've said to him, so I feel like it's unfair to label him as an enabler. I think you would need to hear more from the OP to truly determine wether he's an enabler or not. The limited amount of characters on an FML can make it difficult to fully describe everything that happened.

The point is, OP let his girlfriend leave without him, and now OP isn't doing anything because his mum got jealous but won't take him out. You don't need much more proof that that.

Well, that's where his age would've been a useful piece of information. If he's only a teenager, I wouldn't call him an enabler.

You can't just argue with your mother! Are you insane?!

Judging by the fact that he said he's spending his birthday in his room, it makes him sound like he's under 17, in which case I don't think he was allowed to leave the house. He may be spending his birthday in his room because he wanted to be alone after all that and not near his mom, but I also wondered if it was because he got grounded as well. Either way it sounds like he is too young to have been able to leave or to successfully stand up to his mom. Either way FYL op.

You should go to the kitchen and find a glass of water, dear. You seem rather thirsty.

It was a joke... I don't think he was serious, you guise.

But if thats the case, why is he alone in his room. If his mum was jealous and sad he wasn't spending time with her on his birthday, then she would be spending time with him instead of leaving him in his room alone.

He shouldn't have done anything. It's good birthday, not the mom's. The mom should Have stfu and that's it.

Can you get to the point?
