Most Helpful Guy
most guys have an emotional wall that they hold feelings behind so that we don't linger on them. I'm not one.
Girls feel the hurt of other's as well as themselves more. You may even blame yourself for not doing something right. I think you loved him more so it feels wrong to go out with someone else so soon. My advice is to stop kicking yourself and get out there.
Your beautiful and any guy would be lucky to have you. Be confident in that and you'll find what you're looking for. Don't stop looking until you can find someone who can love you for who you are.
