Yes along with no contact, your ego will become more and more restless wanting to get in contact with your ex. As well your ego will want you to go no contact wanting to hurt/punish or seek revenge against your ex. The important thing to remember is to go no contact to better improve your well being and life. It will be difficult at first but in time the negative feelings will pass and life will improve with you getting better.
Thank you and take care
