Say this: "don't swear, only ugly women swear".
On the topic of paying rent, I think that is EXCELLENT parenting. Even if its just a little rent, its very important that a child be aware of the reality of life. Once out of the family home, life is fvking hard. I intend to make my kids pay rents as soon as they hit 18, it will force them to get a job and/or go to school to make more money. If you aren't paying rent to your folks right now, let me suggest that you start. $200 or $300 pays for your food, heat and hydro and is a very nice gesture on your part... mom and dad keep you and put up with all your bs, the least you can do is give them a break each month. This will also give your parents bragging rights and help them feel more confident when they need to 'let go'. Its the right thing to do.
I will tell you this about your girl: she will seek out a man much older than her. She is going to have a daddy complex, a lot of girls that were raised without fathers are seeking someone to 'takeover' for daddy. She is looking for stability and a man that already has his life together. My wife and friend's wives are almost all the same, mine is 10 years my junior and her father wasn't around. So I would say, unless you are in your mid 30's or early 40's, your chances of nailing this girl are slim to none.
