why is my boyfriend a dumbass who doesnt know what the meaning of romantic is?

I think the meaning of romance varies from person to person and if you don't tell your significant other what you want out of the relationship you are never going to receive it. I know for myself I'm not a romantic person at all, I absolutely hate the idea of getting roses or jewelry and things like that just because I think they are meaningless and I've told my boyfriend that so he understands that. Nor am I the type of person to pour my heart out on paper or anything, but regardless you need to tell him what you expect because he's not going to be spontaneous and do something the total opposite to his character. Though maybe he isn't romantic according to your interpretation of it it doesn't mean he doesn't care, like I said we just have different ways of interpreting and expressing that. So it's not naivety nor negligence I just think if you are expecting your boyfriend to give you something or treat you a certain way that you are expecting him to make that clear.

You can't expect him to read your mind. You need to voice your wants. Communicate with him. Tell him what's bothering you, but don't call him a dumbass. It was quite rude of you to do in your question. Not knowing your partners definition of romantic doesn't make you a dumbass. Not to mention some people just aren't romantic, they can't help it. If it's really that big of a problem then break up with him.

boys don't have the same mindset as us. That romantic sense isnt in them. i have to tell my boyfriend to tell me something nice or be sweet. it works for us. some guys cant think of the right thing to say or do to be sweet. so try and tell him how you feel.

There are plenty who do. You aren't supposed to stick with someone if they don't suit you.

Probably because he's a boy.
I'm sorry, i just got out a shitty relationship, where i had the same problem. I think it may be because, well he's a boy. Perhaps he doesn't actually know what romantic is....have you ever tried telling him?

My boyfriend isn't romantic but I know he cares, I think it's just a thing most males do. My boyfriend doesn't do all the cliche romantic stuff but he's always there for me, supports me through my anxieties, holds my hand when we watch stuff. We all behave differently.
