Health, no I don’t think you should give up on marriage. I think that there is someone out there for you who will truly appreciate you and complete you. AND when you allow yourself to heal and trust again and look for that person you will find her. AND when you do find her, SHE will be your Bracha, your Mazal and will complete you in a way that you will understand what it means to have a true ezer k’negdo and a true partner.
Health, just because there is a reason why you had to go through what you did, that does not mean that Hashem does not have another plan for you, and does not have Happiness meant for you in the future. There is a woman out there who needs YOU, a wonderful man just like you who SHE can appreciate, admire and respect. Maybe a good and better role model for her own family. Maybe just someone who she can look up to and shower with love and devotion. There is an emptiness in your life and there is a woman out there with an emptiness in her life. When the time is right you will find each other and complete each other to become an amazing partnership.
