How the fuck?

I just did the hardest thingI have ever had to do.  

Break up with someone who is in love with you that you love right back.

How am i supposed to live with myself?

She is perfect, she's funny, smart, kind and the best irlfriend ever.

But I broke up with er because of her no good fuck she calls a father. 

He is the only reason I had to break up with her.

He grounded her for the stupidest shit and hated me.

HOW THE FUCK do i go on with yself with knowing that I just broke the person I love's heart?

Sorry for the typos, i am balling my eyes out.
