Sweatpants should not be blamed for the demise of your relationship unless they are a symptom of something bigger. The real relationship killer is your lack of effort.
Yes, sometimes sweats can be an indicator that your simply don’t care anymore. That is IF you only wear sweats around the house, specifically holey sweats that do nothing to flatter your figure, paired with a stained t-shirt, ugly period panties and a mismatched bra underneath, your hair pulled up in a rats nest ponytail, no makeup on your face, and you haven’t shaved your bikini or legs in days or even weeks. Then… you’ve got a problem.
Put some effort into your relationship! Just because you’re comfortably in love doesn’t mean you can stop trying to be sexy. Sure, you’re secure with your situation, you “know” your man loves you and would never cheat on you, but he’s still a man, he still has eyes, and he is still a visual creature- one who wants to be turned on by his woman. That’s not to say that you always have to be dressed to the nines and lounge around in lingerie. But you should at least make the effort to make yourself look decent, and even sexy on occasion.
You certainly don’t want to feel like you have to be “on” and perfect at home. Wearing cute sweats allows you to physically, and therefore emotionally let down your guard, be vulnerable, be real- which is a relationship essential. It’s just to what extreme you choose to take it.
