((TW: This piece deals with sexual assault, abuse and stalking))
So I (22F) and my sister (27F) had always been really close growing up, like joined at the hip best of friends. A few years ago she meets this guy (34M) who she insists is her soulmate but he's a real piece of work. Like almost comically bad, like cartoon bad guy bad. Like first time she brings him home the dog runs up to greet him and he kicks her hard enough to lift her off the ground bad. So parents obviously don't approve of this guy, and sis comes to my room in floods of tears complaining how they never approve of anything she loves and I give her my honest opinion, that I don't like him much, she screams at me because I 'should be on her side' and leaves with him. I feel bad for not being more supportive and apologise to her because I don't want to lose my sister over this, you know? But it doesn't get any better.
Two years ago, sis and BIL get married. During wedding, groom gets completely blatted and comes on to me. I figure he's gotten me confused with sis (we look similar, I guess a drunk can get us confused) and tell sis and best man to take him home and quickly leave myself. Sis is sour with me for a while after, I'm not sure why and she don't tell me, so I'm like maybe she's just sour in general because of BIL? Every time I try to ask her about what's wrong she brushes me off. I eventually leave it.
Despite all this, sis and I still see each other often, but whenever BIL is there it's so tense and uncomfortable. It starts with him just leering a bit and saying some inappropriate things, but then he starts showing up univited without sis. Hanging around outside my flat, work and uni, sending me things, inappropriate texts etc etc etc. I don't recognise this as stalking at the time, but I do now. Block his number and complain to sis, and she tells me it's my fault for being so seductive around him??? I'm pissed off and tell her I'm just the same as normal and how is it seductive to sit around in band shirts and joggers eating burgers? She accuses me of trying to sleep with BIL at the wedding, and when I deny it she calls me a liar and tells me to stay away from her and BIL. Gladly.
He continues to stalk me and I ofc feel really uncomfy and unsafe so I stick with people as much as possible. In fact it gets worse once I'm no longer talking to sis. One evening he corners me while I'm taking the bloody bins out and that's when he manages to rape me, and that's when I get pregnant. I tell family what happened. Sis calls me a liar and tells everyone I've been seducing her husband this whole time. Parents take my side at first and tell sis to never ever bring BIL near the family again. Friends tell me to contact police whenever i see him.
I discover I'm pregnant at the beginning of the year. After a lot of careful thought and soul searching, I decide to keep the baby. Important to note that aside from assault I am a virgin. So people are asking who I've been with, who the dad is, I claim not to know, but sis gets back in touch with the family after seeing me visibly pregnant a few weeks ago and starts demanding to know who the father is. I tell her it's none of her business but she presses because she suspects it's her husband's baby. I do eventually admit to my family only that the baby is the result of the assault, but that I don't think that should define the baby's life and that it's not the baby's fault and that I want to protect it and myself etc etc etc. Parents are demanding I explain my decision to keep the baby so I'm launching into this whole explanation about how I haven't been well since the stalking started, haven't been looking after myself, but now I have this strong drive to protect myself and my unborn child, and all this other stuff about the baby's life and my life and stuff. Like I believe in a woman's right to choose, so even if it isn't the baby's fault where it comes from, if it's better for you to abort something like this go for it, but I've chosen not to because I genuinely believe that's what's better for me. Sis and BIL claim that me not aborting the baby is proof I wasn't raped but instead seduced him specifically so I could have his baby. Mum sides with him this time, going on this spiel about how if it was rape I wouldn't be so adamant about keeping the baby. Dad stays on my side. I get a lot of abusive messages about the whole situation from mum and sis, and sis' friends who have apparently been told I stole the husband (I'm pretty sure mans is stalking and hurting other women because sis is claiming we're still together because he keeps going out for ages and it's all cheaty suspicious or something) and mum is accusing me of tearing apart the family by keeping this baby. AITA?
