Need help!

Hi. Just joined online community and this my first post!

Recently found out my husband has Aspergers which explains lots of difficulties in our 40 year marriage. Don't know where to start coming to terms with this and how to deal with our relationship. Is there anyone who has been in similar siuation who can help? What books do you recommend? There are 100s when u search online!! Hope someone can give me a starting point. Feeling overwhelmed and lonely at present. Thank you.
