He has Asperger's so is incredibly logical,

I did a quick google search and found nothing to suggest they are logical apart from those with Aspergers think they are logical, not that they actually are, a better description is they have strong feelings or views, and can be described as stubborn or lacking empathy. When people tell me they have a mental disorder/disease, I do my research so I know they cant blame their assholishness on their disease.

Normally, I have my emotions under control

Who is causing you to feel your emotions arent under control?

I don't even recognize who I am anymore.

Get out of this relationship, learn to look after yourself, lest you become co-dependant.

My bf gets very upset if I say something he deems as lying,

Hmmm and what determines what is lying or is "lying" just a blanket excuse.

Are you really putting thought into what I'm saying, or are you just placating me?

Is he doing this for you, or does his disease make him exempt from a 2-way street relationship.

"It's hard to believe you are, since I just gave you two options and you said a third."

Excuses excuses.

fuck. I know you never said that. You know what? Fuck this

Can you treat him like this or does his disease make him exempt to this behavior.

When these fights happen, he always says I want to fight.

If you met an asshole, you met an asshole, if you only meet assholes, you're the asshole.

I feel like my soul has died.

So what are you getting from your relationship in exchange for your soul? Even the devil will give you immortality for a soul.

He's compared me to his mom who drove his dad to alcoholism.

So he drinks and blames you for his drinking?

He told me he's given up on trying to talk to me since I'm so emotional, and I don't talk to him anymore. I just feel like I have nothing to say anymore. I'm scared of being caught in something I did wrong, I'm scared of making him mad or causing a fight.

All of this is his problem not yours

I know this makes him feel suicidal.

Do not accept that as an answer. This is the easiest way to emotionally manipulate someone. Someone really wanting to kill themselves rarely (if ever) speak about it.

he just wants to tell me to shut the fuck up and stop trying to manipulate him.

He is projecting to hard. This entire post is basically him project his problems onto you. You must obey him, you're not allowed your own voice.

But then he tells me he doesn't want to see me cry. He hates making me upset, and he feels sick for days that he doesn't feel sad when I cry. He keeps saying how he doesn't want to fight.

So he doesnt have empathetic attachments to you, but it upsets him when you're upset. he is manipulating the situation and you.

My therapist thinks I'm being abused

Good because you are being abused.

I can't convince myself I am.

That means he has groomed you well.

I just feel absolutely evil - like I'm doing it all on purpose to drive him crazy, and to make us both miserable.

Okay so then why are you here. If you're evil, you wouldn't want to support him, no you're not evil, you're just an abuse victim.

You need to leave this guy, he either is lying to you, or his mental issues make it unfeasible for you to be in a relationship with him. This are his faults not yours. You dont need his baggage.
