Is it hard for aspies to end relationships?

[Mod note- Split from a very old thread.]

Well started to read forums so i would be able to understand more..
Im a NT and have a aspie bf.. i quite patient and always been understanding.. the past months i try to shun away from him as i know and feel that my bf is overwhelmed in everything.. him job .. his few friends. family.. well especially me.. but i didnt want him to feel that i dont care abt him.. but i do think of him every day. Im a bit paranoid as just wanted to know if he still wants the relationship as i thought we werent anymore but had a response from an email saying im a still his dearest and still said "yours"..
Then shut himself out again and again missing in action..
Is it just hard for him to tell me he doesnt want me or does he just wants me to keep hoping and to hang on?

It's very hard for me to keep them, and to some length I suppose it's hard for me to end them too. That's just my experience - and when I talk about "relationships" I mean friendships too.

Could be one of two things:
#1. Maybe he doesn't want to come off as mean, so he's just trying to let the pact drift apart by itself?
#2. As you said, he could just be overwhelmed.

Thanks @auxilliary for the response!
We were good friends before i knew he had aspergers.. actually knew abt only when we started the relationship. And i felt that nothing would changed as he was comfortable with me and i to him.. well yes things changed..im just confused if i should let him go or not.. i just dont wanna be the next gurl who dumpped him bec of some complications..and he is so dear to me..he had been telling me that he so brokenhearted bec people leave him.. which i now understands why..
I just dont wanna be mean to him..so i try to be available for him.. but its hard for me to be on a relationship and feel that theres only me on it.
I just wished hed be honest or framk enough.. as i have asked him several times that if he wants out then he just needs to say one word.. "yes!"

I just have to ask.. how can i let him talk even for just a minute to set things straight..

maybe ask to meet with him at either of your homes, or at a place he likes to visit often.

I agreed to marry my wife because I was too polite to say no. She's always been an alcoholic and has got worse and worse over the last 10 years. I want to leave her because of the abuse and the fact that she's drinking all my hard earned money, but finding the right time is almost impossible for me.
My advice would be to try non verbal communication such as a letter or email.

I always found it easy. I'd spend time imagining future scenarios and weighing up the probability of it lasting long term etc.
Once I'd made my decision that was logical to me, I speak/message them saying sorry but I didn't think it was going to work out. If they asked why, I'd tell them. 99% of the time they accepted it and the ones who were more difficult, I'd just ignore them. It seemed illogical to carry on a relationship I knew wasn't working and it would make a break up much more difficult for myself and them in the long run.

It's a black and white issue for me.
