Was I raped?

I'm currently 26weeks pregnant and I'm very tired with hardly any energy whatsoever. For a couple weeks I've said no to sex because I don't feel for it anymore and I've been accused of not being attracted to my partner anymore.

He's recently started groping me and kissing my neck when I turn away and says "I know you like it, you just can't be bothered" so I say no I don't want it and he'll leave me alone.

However last night he did the same, over and over I told him no and I just froze because he got on top of me, moved my pants then told me "it's okay" then he started having sex with me, I felt lifeless, like how could he be doing this to me?

I again said "please stop" and he said "no I love you, just relax I'll do everything"

A moment after he stopped and said "did I just rape you?" "I'm sorry" kissed my head and went to sleep.

I've never known him to be like that. But I'm so confused right now because he's my partner and he said it was okay because we're together and that's what people in love are meant to do. But I'm not so sure.

Was I being horrible due to the fact I didn't feel for sex anymore? Maybe I drove him to do that? But was it rape? I feel like crying because I have no idea what to think.. He's my soul mate and we're having a baby? Did I do something wrong?

It's now morning and he's gone to work and he's being his nice usual self so I don't want to bring any of this up.

He's been violent towards me in the past but since then he's had anger management and he's done very well. I might be thinking too far ahead as I suffer with anxiety&depression; so I don't know if it's my anxiety or I'm actually thinking correctly

Can someone please help me?
