Important disclaimer: just because your girlfriend is losing interest in your relationship, doesn't mean she no longer loves you. Contrary to popular belief, men aren't the only people who get bored with monogamy. Women are incredibly dynamic creatures, who when backed into a corner of mundane ruts and routines will undoubtedly lash out. Sometimes this lashing out will culminate in a hair cut, other times, it will manifest in constantly berating you about how bored they are—why don't we travel? Why aren't you like so-and-so's boyfriend? Why am I even with you? Would I be happier alone?
If any of this is sounding familiar, I sincerely wish you the best. Your safest option is to sit her down and have an open and honest conversation about what can be fixed and what can't. These things are never one-sided, remember that. Don't get defensive, don't turn tables—just talk it out. It's entirely possible that you HAVE become boring out of complacency and comfort. This however, is the solution and while it's helpful, that's not what we're talking about today.
Today, we're talking about identifying the problem. No offense to any of the men reading, but from a lifetime of observation, you guys aren't always too quick on the uptake. There's a reason it's called women's intuition and not the other way around. Again, no judgement—we all have our flaws, right? I for example, deflect every uncomfortable moment in my life with biting sarcasm—it's a problem. That being said, from one human to another, I'm going to help you out. Of course, I can't speak on behalf of womankind, so don't blame me if anything goes awry—you've been warned. P.S. some of these can easily be synonymous with signs she's cheating. I'm sorry, just needed to throw that out there. AGAIN, for posterity—TALK TO HER if you're noticing any of this, will ya please?
Signs She's Losing Interest
If she'd rather spend her weekends with her girlfriends than you (phrases like, "I need girl time" being used more than once a week are 100% a red flag).
If she never answers your texts/phone calls, yet she's always on the phone when you're together.
If everything you say so, no matter how sweet, is responded to with attitude/contempt (the feeling that a person or a thing is beneath consideration, worthless, or deserving scorn). Speaking of contempt, it's basically the BEST sign that your girlfriend wants nothing to do with your shit. Trust me, you'll know it when you hear it. For example, say you're out to dinner with friends and you crack a joke that makes the table laugh. Instead of laughing along, she'll passive-aggressively call you an idiot and ask you to refrain from being the entertainment for the evening.
She's always comparing you to other people as a means of citing your short-comings/failures.
She recoils from affection/your touch.
She makes passive aggressive comments regarding things you've been doing for years. For example, say you two have a favorite restaurant, but when you mention going there she rolls her eyes or sighs. This is a great barometer for boredom. If your girl doesn't even want to eat her favorite food with you, something's gotta give!
She spends more time at work/makes excuses regarding her absence. I guess working late is better than moonlighting at a strip club a couple of times a week, but think about it: she finds work more appealing than you! That's saying something.
She refuses to discuss things about the future/make future plans with you—whether it be to travel, get married, have kids, doesn't matter. If she won't talk about things further down the line than just a couple of weeks, you might be in trouble. Why? Because women LOVE to project their entire futures from the time they're 6-months old. Trust me, I was making college plans from my crib.
Last, but not least, IF SHE TELLS YOU. If you're girlfriend says she's bored, it's not a threat, it's not because she's angry, it's because she means it! Learn to take women seriously and not just chalk it up to hysteria. That shit is from the 1800s. Don't get me wrong, sometimes we say the opposite of what we mean, but every now and then you'll get the balls-to-the-wall truth—acknowledge that and do something about it.
