i agree on a lot of things with you guys.
i'm 20 now... lots of friends of mine (same age) already have the same partner for years and years and are living together... damn, i just don't understand them - aren't you supposed to enjoy your freedom and explore life's possibilities when you're 20?!?! i just cannot make them understand they are throwing away a huge part of their life... man, they haven't even have had a few party-years -- like i'm doing right now, just uncomplicated party and doing whatever i want (+ some study

) whole week long... i think a person needs a couple of those years to find out what he wants in life.
the friends i'm talking about had their first or second girlfriend/boyfriend when they were 17, left highschool at 18, worked their ass out in college for 2 years and now live together with their 3-year-relationship, as if they're both 40 already... damn, i bet in 10 years they'll be regretting their ass out...
and quiet, your story ressembles mine 200%... i'm having relationships all the time but they never last longer than a few months, because:
- i don't want a 'solid' relationship, i think i don't even can do it right now... the girl gets on my nerves when i see her too often... problem is that most of the time the girl wants to be around/hug/talk to me 24/7 and gets angry when i say 2 nights per week is the max for me.
- achieving business goals and study have always been number one and i don't see that change... my business simply does more to me than my girl - ok, i don't tell my girl that in these words but i know it's the truth... you can call me whatever you want but the more time i spend working on my business, the more i get hooked by it... the more time i spend on my girl the more i get annoyed by it...
