How to get closure from my ex? I feel I need it.

Find some reasons to talk to him, then invite him for a drink. Talk to him nicely and show your kindness, your changes and so on

Depending on the situation, if an ex continues to contact you, either hear them out or ignore them. If they ex broke up with you because they decided to pursue another relationship, I would suggest not picking up the phone. Chances are they are only talking to you because they are no longer happy with the relationship they left you for. If you broke up on mutual feelings and nothing has negatively escalated in your relationship, then I say hear them out. But it all depends on your understanding of the relationship.

Look forward. That's the best thing you can do. Look to other people for the comfort your ex once gave you. You don't necessarily have to forgive your ex, just make sure you're not hateful.

Confrontation is a good process to get closure, when you face the person you once loved and loved you back and see everything's different it can immediately make you realise that nothing is the same way and accept that you have to move on. Sadly your ex won't always accept a meeting, in that case you can still ask for a breakup letter where he/she will share its feelings about your past relationship and the breakup. If you're ex chose to burn bridges then you will have to find it yourself, it might be harder, writing will help a lot, going back on what you wrote 3 days before, or 2 weeks before, will make you realise that this (your past relationship, the breakup) does not have such an important place in your thoughts.

If you need closure, you need to firstly figure out what answer you are looking for and secondly what you will do when you get the closure you need.

i would write them a nice message nothing mean. or do the blame game. let them know the good times and bad times you shared with them, and thank for them everything you shared with them. let them know you wish them all the best, and that you also feel happy now, and that you feel like your getting things off your chest. and once you feel like you've said everything you had too say. walk away because it's true closure

Just tell her/he how you feel and if they don't feel the same way they just lost someone very special.

Sit down and have a talk, just go through memories you once shared and have a good laugh about them. Breakups shouldn't be sad and heartbreaking, you take them and make them into something better which later you'll be happy you did.

Focus on you, do your own thing and most of all learn to find and love yourself again. Another important thing, is to block your ex from all your social media accounts as well to help gain even more closure.

You're one heartbreak less from a happily ever after. If they can't see the beauty in you, they don't deserve you
