I also had breakup recently. I also used to think that way. but nothing happened.get urself engaged in some activities you like. don't try to think about him even if it is hard. if he loves you he will definitely come back. otherwise let him go. everything will get better one day.
well honestly speaking patience and time will heal you perfectly. I have been through breakups had a lot of suggestions but never really worked. it's hard but better to accept the brutal reality. the only One thing that probably works best is to keep yourself busy with things like study or work etc etc. think about the progress you have made. that might help to halt the bitterness of the heart for a while. But the only thing that heals it's the Time. yes there will be a time where you will remember the moments you spent with him and feel absolutely nothing. so don't worry. m sure you will get someone who will grow old with you with far more beautiful l,vivid,wild and cherishable memories 😊.. I know it's hard. If you feel like crying, Do cry, cry out loud, it will make you a lot lighter. have a good sleep and start a new day.
