What are your thoughts on me wanting to look for another girlfriend?
Can you tell me why you want a different girlfriend?
I'm so unhappy with my current girlfriend. I want a partner who doesn't have any large flaws.
It's wrong and unacceptable to look for another partner while still being in a relationship as that is being emotionally unfaithful. If you are unsatisfied, you should devote your effort in improving the relationship rather than looking for alternatives elsewhere. If your current partner is making you unhappy and is unwilling to change, you should break up and then go look for another partner as it's very rude and inappropriate to swing from one relationship to the next.
What? I left her already. What would be the right thing to do now?
It seems that you ended your relationship so that you could move on and find someone new. You shoud be sure to heal from the breakup so that you can move forward.
