When you get your heart broken, after some time of finding yourself again, you find someone worth giving your heart to again. It may be scary at first, but you can't compare your old relationship with your new one. There isn't a rule book on when you should move on, everyone is different and feels different ways.
Comparing your old relationship with your new one isn't a great way to start off this. You have to let go of the past and look forward to the future. I know it harder to do than to just say it. I went through the same thing.
For me, it took me almost 7 months to completely get over my ex. Now I'm with someone who makes me completely happy. Those 7 months were long and tiring. I was finding myself and learning to love myself again. When it happened, it felt like I lost myself and I lost motivation for everything. I tried to move but kept finding myself thinking of him, comparing everyone to him. But now I don't even think about him. The guy I'm with now treats me amazing and always wants to see me and watch me succeed.
When you decide to move on, you should find someone who wants to see you grow as an individual and grow in a relationship together. Find someone who supports you through anything you go through without judging you, someone who supports all your decisions and crazy ideas that you want to do. It's also important to find someone you really get along with and have multiple things in common. Someone you can go out and have a great time with but also have fun sitting at home watching movies.
Find someone who you can be your complete self with, that you feel comfortable in the "sweatpants, hair tie, chilling with no makeup on" thing. It really is amazing. Once you find yourself again and you move on to someone who you love to be around and can be yourself around, you just become so much happier with life. Moving on is a hard thing to do in general, but especially someone you were so close with. That's why it's important to find yourself again and to learn how to love yourself and grow as an individual again. You need to learn to love yourself again before you can love anyone else. It's really true, if you aren't happy with yourself then you won't be happy with the next relationship.
When going from a heartbreak to trying to move on, find yourself, learn to love yourself, and be yourself. Don't rush for things to happen, that won't work. Let things come to you and enjoy watching yourself grow as you take that time. Someone will come your way and make you so happy you forget all the reasons why you were sad. Trust me, your day is coming!
