first and for most you should never Charge who you are for a person. And not talking Major things. Small Changes to build a healthy relationship are key act... Self care, trust building, being more open, fitness. Things like that are key but black carding friends is not healthy for yourself. And anything to do with your past if he truly loves you for you, your past shouldn't matter thats not the Person you are today. Everyone has a past that is what makes us who we are today as long as we are better then we were before. So he should be proud of the person you have become not who you were. And how Many people you have been with before him Shouldn't be a Concern, we call have had Past relationship. It that is a main Concern for him then he has In security issues. And to be honest from what you explained he seems some what Controlling, and that Could be a big red flag. Please remember to be yourself and love who you are today not yesterday...
