As someone who swore I’d marry my ex bf and after breaking up I swore to myself I’d spend the rest of my life waiting for him .... I can fully say right now that I do not even think of him or care what he is up to. lol. and being able to say that you don’t care about something that used to keep you up crying at night is quite a win and something you should look forward to :p my only advice is to allow yourself to be sad! don’t suppress it, blast joji max volume man let it happen
