What the FUCK does his future education and career path matter to you, you plan on putting both your names on a shared crib and a whip or two? Gotta make sure hes financially stable when you adopt a couple kids??
And your girl doesen't like him? I bet thats 90% of the reason you think you shouldn't hang with him no more....
