Dating in the chemistry world is brutal! The meme shows you as Helium (He) - an inert noble gas that literally refuses to bond with anyone. Meanwhile, the girl you like (Carbon) forms four bonds easily, her boyfriend (Fluorine) is super electronegative and aggressively forms bonds, and her ex (Oxygen) readily forms compounds with almost everything. Even her brother (Chlorine) and father (Nitrogen) are more reactive than you!
Your problem isn't just being "noble" - you're literally the chemical equivalent of someone who won't commit to a relationship! Maybe try being more like Sodium - a bit explosive, but at least willing to give up an electron for love!
