She sounds like a 19 year old trollop that will just cause you frustration. You're a naive 21 year old boy. Let her go and move on with your life. You probably shouldn't even think about settling down until you're nearing 30. You need to sew your wild oats. Get it out of your system when you're young. You are both far too young for a serious relationship. You don't even understand yourself at this point let alone what you want/need in a partner. I was stuck in a terrible relationship for 3 years from age 19-21. Then I tried online dating for a while... went out on dates with easily over 100 different girls over the next 7-8 years until meeting a girl I legitimately enjoyed being around. I'm only 30... I still don't know what the heck I'm doing. There are people far wiser than myself on this forum. But I sure as heck know that at 21 I was clueless and my life would have been a disaster had I stuck in that first serious relationship.
As I'm sure everyone else is saying, you're going to look back on this little 6 month fling and laugh about how silly you were.
I mean really... what's the chances that your serious match just happened to be some teenage strumpet who worked at the same job as you. It's a big world out there... she's just some random.
Also... from age 19-25 people tend to change dramatically. There's pretty much a 1% chance of it ever actually working out with this child harlot long-term. Plus, if you live in the Northeast, there's a high probability she's going to gain 50 pounds and succumb to a crippling drug addiction over the next few years anyways.
As someone from the northeast who met his wife at 21 years old and been happily married for almost 5 years, I couldn't disagree more. God knows where I would be if it wasn't for her. Idle time is the devil's plaything.
It should be noted that my wife gained like 10 pounds, but she was a little too thin back in the day so it's all good.
I mean there are exceptions. Congrats to you. In general, the 19 year old girl is going to evolve emotionally and intellectually over the next several years... or he will... or both. It's highly likely they will grow apart. The girl I thought was my "true love" when I was a 19 year old kid working a dead-end job was some airhead blonde who worked at a grocery store. 11 years later, she's still an airhead blonde who works at a grocery store and I'm at a completely different place in my life with completely different interests and completely different hopes and dreams.
"Those who marry when between the ages of 20 to 24 have the highest rate of divorce. You've probably heard people say that 50% of all marriages end in divorce. And while this is kind of accurate, it's also a bit misleading. As it turns out, age plays a big role in determining a marriage's fate. Those who marry when between the ages of 20 to 24 have the highest rate of divorce. These couples are nearly twice as likely to get divorced as those who get married between the ages of 25 to 29 years old."
Consider yourself lucky. It works out sometimes. I highly recommend against it, though. Too many [dang] people in this world. If he's already having trouble with this 19 year old trollops now, it's likely only going to get worse. No sense in settling for the first girl you fancy who happens to work with you.
I guess there are other factors that could lead to success. Maybe you get lucky, meet a girl in medical school with the same life goals and interests... maybe you get married young, evolve together and stay on the same trajectory. Maybe you meet your girlfriend working at Pizza Hut when you're 21... she's a cute vapid blonde, you're a meathead jock. Maybe 10 years later you're both still working happily at Pizza Hut with the same simplistic life goals... Happily ever after. Or perhaps you're both a couple religious nuts with the crippling guilt of a biblical cloud zombie overlord dictating your entire life... you crap out kids young and live the rest of your life moderately content. I mean, it could work. It does work sometimes. Kudos to those who get lucky. I just know that I personally am an entirely different person than I was 10 years ago and in retrospect I couldn't tolerate dating my ex for a week let alone 3 years. And I'd say clearly FAAAAR more often than not, the guy/girl you date at age 19 is not the person you spend the rest of your life with. So there's no use sulking over a temporary fling that will inevitably be a small blip in the grand scheme of your life. Merely a cameo in your overarching story. Don't stress it... But save the pics. You'll definitely want to save those pics.
