I can imagine how much pain you might have gone through, and how much hurtful it was for you to sacrifice your love for your family. And yes, going for such marriages which bring back the same regret and trigger the pain will be indeed difficult for you, so why not stop forcing yourself to be in such places and involve that time to acknowledge your emotions and let yourself grieve?
It is okay not to rush yourself to be in a relationship when you know you are not ready, but I feel some work needs to be done in accepting the fact that the new person or anyone, in that matter, will not be your ex. Every person is unique and will have something different to offer you, but to see that and make peace with that fact- your past baggages need to resolved. I therefore, encourage you, to connect with Experts on this platform ,who can help you with that. Maybe give it a try once!
