is it wrong that I don't want to allow my son to have a girlfriend?
Why block your kid from getting a girl?
I love my son too much to see him being beaten up by a girl.
Getting into a relationship doesn't equate to getting beat up. If he's old enough to understand and interested in a relationship, let him pursue it. He'll have a learning experience.
What makes you so sure he can handle a girl?
You will never know if you never let him have a chance. You need to give him more freedoms to see what he wants and how he handles life.
