Welcome to SI. So sorry for what you are going through.
He mentioned that I am just insecure...I told him trust had been broken & was hurt....How can I make him understand ??
That is an odd thing to say to someone that was recently betrayed. What was the context for the remark? Was it just in general, or in reference to him hurting you? If it was the latter, perhaps your fiancÚ does not believe infidelity is wrong. There are a lot of people these days that see nothing wrong with having sex outside of marriage.
Before getting married, you may want to have a heart to heart with your fiancÚ to get his views on fidelity to make sure they align with yours. If they don't, you may want to reconsider the marriage. It's difficult to change someone's core beliefs and values. Your fiancÚs lack of remorse, and compassion for your pain, sound troubling.
