I guess.. i haven't told anyone and i dont want to until we bith decide.. guess they r close n he is probably nervous and excited.. ill definitely mention it to him
ITS OK MY HUSBAND DID THE SAME. They just have a close bond.
IMHO I think you might be overreacting a little bit. I definitely understand wanting to keep it a secret and it definitely is a problem if he is lying to you. But he is just excited and it is his brother. You haven't told your mom or sister or best girlfriend? Even if you have kept it a complete secret from everyone except your bf the relationship he had with his brother could be a deep one. Just be straight with him, don't play games. Sit him down and say you saw the text and it hurt your feelings that you told your brother and then move on.
