Help please???

So I've been questioning this for a while. a couple years ago I had a boyfriend and we would be cuddling or kissing and he would want to push it further. I told him no but he kept asking until I said yes or would stop and act passive aggressively or give me the silent treatment until I engaged and said yes to sex. Is this rape because I felt pressured, or not because I did say yes every time.
