should I send a happy birthday text to my ex boyfriends sister?

nah... I wouldnt.
it would be one thing if you guys really were friends, like real friends.. then yeah, you shouldnt let an ex get in the way of that. but it doesnt sound you really need this girl in your life.. if she was a friend worth texting, you wouldnt even need to question it. in fact if you're really honest with yourself, you probably only really want to send her a text because she is a connection to him, not because you care about the outcome of her birthday..which is totally understandable, dont get me wrong. but I think it just might be better left unsaid. shes not pacing around her room wondering why you didnt wish her happy birthday. she wont even notice. but if you DO text her.. her first thought will be "wait.. I thought they broke up." and then her immediate second thought will be the assumption I made above. just a sad attempt to hold onto some connectedness to her brother. (whether its true or not, thats what she will think.)
