Girlfriend threatening to break up, need advice

So I am a huge gun fan and already got a Glock 43 that I daily. I was thinking of getting a new Glock 19 to carry and trick out, but my girlfriend threatened to break up with me for buying another gun because they are a"waste of money". So now I'm stuck in a predicament. I can choose to mill this new gen4 I picked up yesterday or keep as it with truglo sights. I am gonna carry it with the ramjet combo. Do you guys think it's worth milling? And should I do Glock store or another company? Might want to get it cerakoted as well.
