I still like my ex boyfriend?

[Daniela]

So long story short...he broke up with me a long while ago and he still wanted to stay friends....so we stayed friends. Anyways these days on the social media he added my sister and he asked her how she was...and how my brothers were doing...he also told her to say hi to them for him. When we were together my brothers were not really close to him...they got along but they werent buddy buddies. And then the other day my sis put a picture on instagram of her and one of my brothers and he commented "tell him I said hi" sooo what does all this mean..im confused. ...advice...please no rude comments
