The fact that I won't ever see her again in 2 years or so + the fact that it's not a necessity and since most of the people having gf issues here are probably going through puberty, thus it's nothing more but a physical attraction, IMO a waste of time and money, yes, that is a reason not to be in a relationship.
Look at all of these threads. Ladios' girlfriend was lesbian, obviously doesn't even know herself yet, YoungLink's or w/e gf was flirting with his friend, etc.
Again, I don't need to be in a relationship, it changes nothing for me. My life will be the same without them as it was with them.
