Was it a nasty divorce? I take it you are not on good terms, if this is bothering you. I can see why it would upset you, I don’t think you should be crying over it though. You have moved on from your ex-husband, and are in a happy relationship now. Your brother remaining friends with him shouldn’t affect you. Are they hanging out, buddy-type friends, or just facebook friends? I personally don’t see what the big deal is about Facebook i’ve even made a question on here regarding it So don’t get worked up about it. I wish your brother weren’t so insensitive about it though. Did you calmly explain why it hurt your feelings?
