I want to really be friends with my ex,,but theres an akward silence?

okay well how long have you been dating? if u were datong for a short time then it shouldnt be so awkward. if u were dating for a long time then its probably awkward because he still might like u, idk if u still like him, and he just doesnt know wht to say because he still has feelings for u but he doesnt know what o say because uve probably been going out for a long time. its also awkward because if u were like making out before and now since ur not going out u like have nothing to do or somethingg.... what u should do to break the silence is talk about something thats going on in ur life or talk about something that u guys both like. i hope this works outt!!!
