AITA for wanting to keep the baby?

This is hard to talk about, so forgive me if I seem cold. I have to get this out. My husband (34M) and I (34F) have been together since high school. After graduating, my husband enlisted in the Army. After boot camp he came back and proposed to me, and we got married. He said he wanted to start a family, and I was excited, so we immediately began trying. After no luck for a couple years we finally decided to see a doctor. I was fine, but he is practically infertile (low sperm count). It was devastating for us but we have learned to live with it, and considering adopting and other options. I love my husband more than anything in the world, so even though I have wanted a baby for so long, I am not going to leave him because he can't give me one.

Several months back one of his friends from the Army came to visit. They were having a good time reminiscing and drinking, but I had to work in the morning so I went to bed early. I have trouble sleeping and take medication for it, so I'm pretty much comatose. According to my husband the alcohol ran out, so he walked up to the corner store to get more. While he was gone I awoke to his friend assaulting me. I tried to fight back hard, and he eventually ran off. The neighbors heard me screaming and called the police. My husband was inconsolable and blamed himself for leaving me alone with him.

Before anyone suggests it, we are both in therapy, individual and couple therapy since after the event happened. It has been helpful.

Fast forward to now, and I am pregnant. The problem is, I feel like my husband is going to want me to get rid of it. That was actually my first reaction as well, but now I don't want to. I know it's insane, but I never thought I would be a mother after finding out my husband can't have babies. I didn't want to be with anyone else. I have to sound crazy, right? I mean, I can't possibly be ok with this. But all I can think of is it is MY baby, not that horrible man's.

I am so scared to tell him I want to keep the baby because I feel like he will want me to terminate. I'm tempted to just wait a bit longer before telling him, then terminating it won't even be an option, but then I will have deceived my husband, and might lose him anyway.

How can I keep the baby and my husband? I don't want to have to choose, but time is running out. I have to tell him. And I feel like if he tells me to terminate it, I might actually choose to leave him. I've never imagined a life without him, I've never felt this way before and I'm so conflicted.

AITA for wanting to keep the baby, even if my husband doesn't want me to?

TLDR: I was SA'd by my husbands friend, and now I'm pregnant. Husband is infertile and I'm afraid he will want me to get rid of the baby, but I want to keep it.

Edit: Wow, some of you are truly very cruel. I did not say I was definitely going to keep the baby or that I was definitely going to wait to tell him. I said all of the different thoughts going through my mind. But some of you telling me you hope he leaves me and that I don't deserve him just because I have these thoughts, I truly hope you or your loved ones never ever have to go through what I've been through, and have to make the decisions I have to make. I just found this out myself and am working through all of this. I can't stop crying and he knows something is going on.

To those of you with what I consider "tough love" but still gentle comments, thank you. Those really helped me to see what I could lose if I didn't let him in. I do not want to lose my husband. I WILL tell him.

With that being said, I mentioned in my post that we are both going through individual counselling as well as couples therapy. I left a voice message for our couples therapist to get an emergency session. I feel that is the best place to tell him. I also requested an appointment with obgyn. I am waiting a callback from both offices. I am going to tell him and we will make this decision together.

Can a convicted S..offender get custody of a baby? That seems insane. I definitely do not want to deal with him any more than I already have.

For the commenter asking about rape kit and morning after pill -- yes I did. But I also was throwing up a lot so I don't know if the pill even stayed down. Also, because I fought him off we don't think he "finished" but I know that doesn't matter when it comes to pregnancy.

We did consider invitro, talked about it at length but chose against it as it was too expensive and other personal reasons. We decided if anything we would want to adopt since there are so many children that need loving homes.

If any of you want an update please let me know. If not I won't. A lot of you seem disgusted by my indecision and it really hurt to read. Maybe I'm just too sensitive right now because of everything.
