Yes, you can truly move on from this person.
Trying to see someone else when you haven’t gotten over this other person is not a good idea.
It will only end up putting you in the position that you found yourself in.
You constantly had this person in the back of your mind even while you were dating this new person.
If things didn’t end well or were rocky, there may be a part of you that is also seeking closure.
Hence, you may be experiencing two different emotions.
You may be feeling the desire to get back to how things were when the relationship was going well and if you cannot get that, you may desire proper closure.
These feelings may be the source of your yearning when it comes to this person.
Something that can help you truly move on from this person is to let go of those two emotions.
The emotion that desires the relationship to come back and the emotion that desires closure.
Let those two emotions go.
The best way to do that is to focus on yourself currently.
Avoid getting into any other relationships right now.
Instead, start figuring out what it is that makes you feel unique and special.
Focus on building more of a sense of independence and understanding of yourself.
Truly accept that the relationship is over and will never return.
If you’re able to do these things, there’s a good chance that you’ll be able to truly move on from this person.
But, you have to put in the effort and the time.
