I have just intered into a new relationship, but still can not overcome previous one...please?

Bad idea, you don't need to rush into another relationship...especially if you're not over your previous one, trust me! You need to give your heart time to heal & get over that person! Yes, right now you may feel like you will never get over that person, but time heals everything! No matter how long it takes evidentially you will be able to move on! Your new partner could by the key to that, mine was, but just take it slow, don't rush & if they truly love you they will help you through this & give you time! :)

You should not enter a new relationship if yo are totally not ready to forget the past. The new relationship may not be successful.
