Is this rape ..

I feel very dumb for not knowing the answer myself...a few weeks ago me and my boyfriend (now ex) were making out and he was fingering me and then he wanted to have sex and I told him no because he didn't have a condom .he proceeded to tell me how I was no fun and how he would be happier with a girl that lets him fuck without one .i just listened but then he started pushing my legs apart and was trying to put "it " in me and I repeatedly said no ,he is stronger then me he obviously won and I cried the whole time i said no over and over .i finally gave up and just layed there crying ,to me I felt like it was rape but is it ..we had been dating for 2 years ,we had been sexually active for a while ,I stopped fighting him I gave up and payed there is it my fault for not trying harder ? ..ever since this I have been very depressed and I feel like I will never move past this and I am just at the point where I want to give up .

Ps I broke up with him two days after that because he cheated on me to have sex without a condom .my life is just full of shitty problems
