My boyfriend has the "it's just a fish" mentality when I go and spend $70 at the pet store for new decorations, water care etc. But I'm the same way...I make myself put the computer down and actually have a life. I'll occasionally stop what I'm doing just to look at my tank and make sure Dumbledore is still swimming and happy. Don't worry, you just got the betta bug :P
