I feel like my ex is gonna see that im finally give him space and hes gonna say something like “so i guess your gonna not talk to me anymore?” Even after i tell him about no contact
He is your ex and he should not dictate the terms by which you live your life. Nor should he influence your decisions. If you choose to do NC, it’s your decision and you do not need to get his approval. After all, he chose to leave the relationship! I feel he is still trying to manipulate you (basically, an attempt to maintain control over you) and you should not allow that.
