Hey Bryce Im sorry to hear this, I know how it is to be young and have kids, I had my first at 17 and had 2 by 20 years old... Its tough on any relationship, nevermind a relationship between two people short on life lessons.... You tend to learn things after things happen to you, I can stand here and say, this is this way and that is that way but until you learn for yourself, its all just hearsay...
I went through a lot of relationships some lasted 6 hours with both of us happy and never seeing or talking again{Them are the fun ones} and some lasted months ending with hard feelings and a little lesson {If you are smart enough to learn it}, then after many of these I figured it out....
You need to find someone you can stand, you can have a conversation with without thinking, WTF is she thinking, someone you want to have it all with and will give it all up for.... But more importantly someone that feels the same way.... You see then, no one would have to tell you how to make it work, because it already works automatically... I hope Im explaining this rite, I had relationships that I had to work for and it sucked and ended up not working...
This is where I don't agree with a lot of other people that say marriage is hard work and you always have to force yourself to listen and be kind, and curteous, ect.... When you find the rite one, that comes with out trying, I love to hear what my wife has to say, and I can tell when Im talking she feels the same way... She talks to me about her day at work, I talk to her about mine, and we do this because we want to... I'll admit Im not passionate about all of her endeavors, like crocheting/knitting, Vegatarianism/Vegan what ever, and teaching kids how to dance BUT I also don't have to pretend to be, because she hardly brings it up, she tells me whats going on but she doesnt want to talk to me about it because Im not super interested. And I don't come home telling her about hunting, and the hot rods or motorcycles, ect... Because although she laughs at how "into" it I get when I talk about it, I know she 1- hasnt a clue of what Im talking about and 2 would rather have a 5 minute hug than a 5 minute conversation about the new all steel fenders I got for my 32 ford.....
So I hope this made sense, IMO, a good relationship comes with out trying.. Now don't misunderstand this, a lot of people argue, and you should know when something is wrong... A quick story for you...
A friend of mine was married with a son for about 8 years, he started fighting with his wife all of the sudden, and it was bad, like going to get divorced and sell the house bad... Turns out her boss at work was harassing her and they needed the money so she was putting up with it, this slime ball rubbing his pecker on her and grabbing her tits for 3 months!!! But he thinks its something else of course it all happens when money is tight and, thats all it takes... They never got divorced, because someone at her job told her husband what was going on, and they actually got a settlement for over 100K$ after my friend found out he new what to do about it.... Im not saying someone is harasing your girl, just there may be more to it than what you see, so look harder...... But don't live miserable, don't spend a lifetime trying to fix something with missing pieces is what Im trying to say, its not good for you her or your son.... We only get one shot here, to not be happy for as much of it as possible is a waste....
Good luck bro...
