It depends, most of the time we are happy if we want to be happy,

it depends on the individual... If you do have a girlfriend then good 4 you, make sure she is the right person and nothing bad will come out of it. Not all people are happy in relationships, because it is either one sided or they are not compatible for each other.

I don't know dude but i think it is an important quistion !!! but I think Munkelman is right because both of them are normal or good for you and you can manage anyway if it's not. Mabaet also has a point to who failed in relationships or don't care about or itsn't an essential thing for them to begin with.

maybe both cowboy...

I think, guys having a girlfriend become happy easier, but you might also manage without one.
