Tantrums in Asperger adults

Hi there, I joined as I need some guidance, I love my partner very much who has Aspergers. The only issue I find difficult is that he starts fights with me non stop and takes so much energy to reassure. He is controlling, suspicious and jealous.

Mostly I am patient but 10% of the time I get annoyed as he is so controlling and I find it hard to breathe. (not literally)

His outbursts then become uncontrollable and although he is never ever violent he is emotionally volatile and its impacting my career and health, I am a very social person and my career also requires me to socialise, 

90% of the time we are so happy and love each other so much, is there medication that may help him calm down? I dont wish to drug his personality which is ace, he is amazing and so very clever, honest and kind but I am so tired of these patterns.

Can you help?

Thanks
