I'm going to fail my classes
Why are you trying to fail your classes?
I got a girlfriend and i don't study anymore
You're not supposed to ignore your college and pursue relationships. It's great that you have a gf but you should focus on your studies. You can always do both!
I love my gf and she loves me. I can't imagine my life without her.
Then study so you can have a better future. Get a good paying job and buy her a house and have lots of kids.
