Girlfriend told me to suck her dick last night

Morning all,

Relationship issue today

Long distance relationship. She cant control me and know what I'm up to all the time. If I want to get high then that's up to me. Whilst your at uni let me have fun before i get a ball and chain.

Anyway i need some views on this. Its not that i lie to her its just i cant tell her certain things because i know she will blow her top, things that she doesn't like me doing.
I'd never cheat on her but i bet she wish i did because i have a feeling she wants to break up with me but she cant so is stressing me the fuck out so that I break up with her, which is ball ache because she is fit and i don't want to break up with her but i don't want an argument over small things.

Good thing about long distance is that I could do this over the phone and not see her again, but i left a few things there so I'm going to do the right thing and go round tonight. Plus i left a few things round there last week.

I know she's at uni and all but i don't want her to take the stress out on me, and this isn't the first time.

So to put a long story short, should i break up with her before she breaks up with me or try and ride this out? or is the weed making me paranoid.

Oh and she actually did tell me to suck her dick last night, that was the last thing she text me last night after she told em to fuck off on the phone for laughing at her accusations of me cheating on her.
