He doesn’t want sex anymore

Me23 and my boyfriend26 have been together for 2 years,

last year unfortunately I became pregnant and it turned out it was a molar pregnancy(2019)

I was heart broken, confused, and felt lost. We’ve started living together now for about 4 months, we love each other very deeply but he hardly touches me anymore. We have cuddles a quick kiss on the lips and he looks after me we laugh play games cook together, But when I try to become sexual he flinches, he pulls me away and I can sense the uncomfortable tension so I always respect his feelings and never pressure him. I’ve asked what’s wrong I’ve communicated I’ve told him how I feel and he always says he understands and nothings wrong and that he doesn’t know what to say, but I keep feeling forgotten. We’ve had sex 3 times in the last 5 months. Sometimes I feel like the reason he doesn’t want to touch me is because of the molar and it makes me feel like my body is a monster and his scared of me. I feel like I’ve done everything I can do and I don’t know what to do anymore I just want to become distant and it’s breaking my heart that someone I love isn’t giving me the love I need to feel for the relationship to survive fully
