Husband wants a divorce and I want to atleast give it a fair try

Dear alll , This is a super complex case . We met in 2014 via shaadi.com After a year of knowing and understanding each other (no physical activity) We clicked very well 2015 we got married with blessings of the family. As I was a virgin ,we really in our honeymoon that I am very scared of sex . I was diagnosed with vaginusmus which is nuthg but failure to consummate . We tried. Lot but unable to properly have sex. Both were very sad but we loved each other so much and attached to each other . He always said kuch na kuch ho jayega . We lived a fun and opulent life . 8th year of marriage we started Ivf which he wanted me to do to have children. Which he supported completely. Midway he got second thoughts n he started getting nervous that now if children come he will be stuck with me .so he left home July 2023 I conceived twins but he made me abort them saying we should try to fix our marriage and I agreed and I also said ok for abortion. After the abortion also he dint come back to live with me saying he is confused and need to think . I gave him his space .meanwhile we spoke a lot and after few months he said let’s try .but he never came home . During that time I did my treatment of vaginusmus and I am completely fit now . He was getting close mentally slowly but now his family has started complicating this situation more . Saying giving this chance is a Bad idea . Now it’s April 2024,and since feb even I suggested let’s call this off if you are not interested and he was like let’s try . Now he says without any trying or attempt let’s call this off it’s too complex for us to get out of . What do I do ? I love him a lot and I know he does too . He is just a little weak at heart
