Considered Rape?

It scares me still and makes me soooo sad to think of it. He was my boyfriend, not anymore. One night we were cuddling in bed watching a movie when all of a sudden he got up and tried to take my leggings off. I told him no. He still never listened. I tried to stop him. somehow he managed to get into me. it was horrible. i was crying while he was at it. im 22 and it happened a few months ago. i feel like im at fault for this because i was cuddling (i likeD cuddling with him) with my legs over his. 😞 would it even be considered rape even though we were together (we were together for almost 8 years)? i have been so scared. im scared no one will believe me. 💔 how do people cope with this? it makes me want to cry because i was so helpless crying. help me.
