i dont know what to do

on Friday my boyfriend and I broke up or should I say I gave him a choice between continuing to play stupid games and ignoring me or to just break up and he chose to break up. Over text I might add after a two year relationship . Naturally I never really thought that is what he would choose I mean we shared so many firsts together and I really loved him and love him still. An our after our break up he posts about catching feelings for someone else so I blocked him on every single social media I had him on because you can't just start looking someone it has to take time . I needed him today or someone it was a really horrible day and usually he would actually help in these situations .I mean I feel so stupid I miss a guy who used too tell me that I'm useless and that I'm childish and small minded and stupid when he couldn't get his way .I just I miss him but I feel so wrong missing him . There must be something wrong with me right ? I just need advice how do I get over him when I fell for him so deeply ?
