ENGAGED TO BE MARRIED + FORCED SEX = NOW PREGNANT

I'M 27 HE'S 35

Me & my fiance has been together for 3 years & engaged for 4 months **HE HAS NEVER DONE ANY OF THESE THINGS OUR WHOLE RELATIONSHIP THIS WAS A FIRST ** & This happened 3 months ago our last night on vacation before catching flight back home .. everything was perfect until this night.

We went on vacation he wanted to celebrate our 1 month of being engaged & me not backing out so Boom so we're leaving the restaurant I unexpectedly run into my ex whom I miscarried from (7 years ago) we both were 20 I'm 27 now when we saw each other we hugged he kinda lifted me off my feet & ig his hand placement was on my lower hip/back area & ig we hugged too long & gave each other a side cheek kiss before he walked off. I briefly introduced them & I said proudly THIS IS MY FIANCE. On the way to the car my fiance's whole mood changed he didn't say anything to me the whole way back to our sweet so we get there & as I'm taking my clothes off to shower I'm asking him is everything ok & he proceeds to ask me was that the ex I miscarried from I said yes (while still undressing) I get in the shower he comes in asking question after question.

Why did he (my ex) hug me so long

Why was his hand that low

Why was he gripping me like that

Why did we kiss (mind you my fiance kisses me that way a lot because he is a gentleman & it's a polite way to greet)

I ask him to let me shower & we will continue when I finish & he does. The moment I get out & go into the room he proceeds to say so I let him ( my ex) be the first one to put his seed in me this & that & how we've been together this long & we're engaged & how I try to push him from inside me before he ejaculates but I let a dude that was just a bf impregnate me Blah (HE WASN'T YELLING AT ME JUST LOUD TALKING ) while he's saying all that he's taking his clothes off he then walks over to me ( mind you even if I did plan to f*ck him that night at that point I was 100% turned off sexually) so I didn't want to when he gets to my side of the bed he snatches my towel off throws me on the bed hits the light as I'm asking him not to do this like that because he's upset & we both have been drinking he gets over me he's rock hard I'm asking can we talk about it like adults he says we are talking once he's inside me one hand on my neck the other pinning my wrist down as he's in & out of me he's saying how he's gonna be the first to successfully impregnate me how he's mine & I'm his & how this is going to be both our 1st baby together this & that atp I just let him do his thing BUT I know when my fiance is about to ejaculate whatever part of my body he's gripping he squeezes very tight before he releases this particular time his hand was on my neck & wrist at that point i did continue to try to get him from inside me because we agreed no baby until we are officially married but the closer he got to finishing the tighter his grip on my neck so i laid there & just let him finish inside me he also fell asleep inside me i just laid there for about 10 minutes i went & washed myself up washed his area for him with a warm rag ( because like I said he was way drunker then me) put the cover across him got under he grabbed me cuddled me we went to sleep I AM NOW 2 MONTHS PREGNANT FROM THAT NIGHT he's nowhere near violent him having to much to drink & getting upset made that happen he blacked out he only remember bits & pieces he asked was he ruff I said a little he asked did he hurt me I said a little he broke down apologized but I never told him exactly what occured so idk just wanted opinions on the situation.
