Does this sound like my gf will break up with me?

You have to decide if the relationship is worth the heart ache that you are feeling. Time will tell if the relationship will last , but you will get through it and life will go on. There are more girls that you will have more in common with and maybe not so high-society. Just ask her if the relationship is fizzling and why she is embarred to be with you.If she truly cares she would not let her friends treat you bad.
