I think it's weird that I don't want a girlfriend. Don't you?
Not really. What do you find weird about it?
I'm afraid that I'll be bored and my gf might get bored of me.
You're making assumptions about hypothetical situations. You never know, things could turn out great. Regardless, it's no big deal to not want a partner.
Whatever man, I don't think I will have a gf anytime soon.
And that's fine if you ask me. You're not required to have a partner.
