The Fucking Shit That Comes Out of My Mouth

I've been with him since I was 18 and he's my first boyfriend. We're saving for our own house, but are currently living with parents. He is also going out drinking and not coming home. This has been an issue throughout the relationship. Is this just a rough patch? No. we're making big steps in our lives and are serious about getting a house together so I want to get someone's opinion before things get real. Fucking break up with this twat.
