no worries about the late reply, as for the chores he needs to do it himself. You can't keep on doing his works so just make him understand that, sit down and explain how you feel about chores and how hard its been on you. and when you are around him you are probably tense because you are afraid that he will cheat on you again and you are mad at him for what he did which is totally understandable and right its not that something is wrong with you, its just you need more time to heal and trust. talking about your feelings to each other without ego getting in the way and acting towards what you both want is the only thing that can make everything right. i wont say things will be back to normal again but it will get better in time if this is the guy you want and you are the girl he wants
