Was I raped? Please answer

Long story short I was dating this guy & at first I wanted to have sex with him when I went to his house but then he told me he didn't have a condom so I changed my mind he forced into me & kissed me although I said no multiple times and said he would pull out & I still said no but he kept going I just stopped I didn't say or do anything I let him finish today I told my mom a former rape victim about it & she said I was a slut & because I didn't fight I wasn't raped & I put myself in that situation Thank you to everyone who has commented
