Trying to move on from someone you thought was the one is difficult.
You put so much time and effort into them, and without them, it feels weird. You plan so much with them and for your future together for them just to leave. It hurts.
It may feel like you can't move on or that you don't want to.
Maybe you aren't ready for something that may be real again or you're afraid that you may get hurt again. But sometimes you need to take that risk and try to find someone who will make you happy.
Whether you are single and having fun making new friends and hanging out with new people or just focusing on yourself, it is better than sitting at home, upset over something that you can't control or change. Moving on from someone who was a huge part of your life takes time.
Taking the time to get yourself back to how you used to be is an important part of moving on. Finding yourself again, doing the things you love, old friendships that were lost when you were in a relationship... Everything changes when you move on.
And when you're ready to move and find someone new, make sure that you find someone who matches your personality... That you can have a good time going out with like drive-ins, dinners, or even to friend's houses together; but also that you just enjoy spending time with, whether out or just by yourselves.
And don't rush it if you aren't ready.
The person you are looking for will come one day and till that day comes, enjoy having fun and focusing on yourself. Making sure you love yourself is important and you can't find a new person to love before you love yourself.
