A week ago my 4 year old son was diagnosed with high functioning autism. At the time of the diagnosis my husband was staying at his parents house because we were having disagreements and I made him leave our house, it was a pretty big deal and for a cool off period. After informing him what happened at the doctors he cried and begged to come home and let's move on, I said no, I was having a hard time dealing with what I found out about my son and wanted to be alone, anyhow he asked the whole week to come back home calling and texting and I ignored him and told him no, he told me he was hurt and I still ignored him. Well 3 days ago he tells me he is living with another woman he just met and she makes him happy so that's where he is going to be, my heart shattered I begged him to come home and he said no I didn't let him come home when he wanted to and that hurt him and he never wanted to feel that hurt again, I have cried and begged him to come back home and he refuses he tells me he's happy where he's at and he doesn't want to leave I've asked him how can you throw away seven years over a week,  he said he didn't know but he couldn't do it if he will work. He also wanted to take this girl to Thanksgiving dinner at his parents house which is very unusual for him to open do something like this I mean even living with another girl it's saying he's not coming home is unlike him he's never been like this before. We ended up doing Thanksgiving today at his parents he acted like he didn't know me he was detached  from the kids and didn't have very much interested in them  he spent money on expensive shoes and clothes that he never does and it was so different everything about him was not him I've cried and cried and cried to him and all he tells me is we will see where things go he told me today he wasn't staying at his moms house he was going to stay at the girls house he has been so careless,  which is unlike him,finally his mom called me today after Thanksgiving and asked what was going on with him she said she felt on edge today because he acted very weird I told her that I greed she also said that he told them he was happy with this girl and he wanted to be with her she said he seemed very adamant about it and it was weird for him to do something like that. She also mentioned that since our soms diagnoses it's like something snapped in him and he became someone he's not and she's noticed he is detached from the kids. My husband is a family man a provider and crazy over our kids. After a week he is changed. I call and call he put me on block I text and text. I try to give him space and back off but it's hard I love him to death and it's heartbreaking I feel he's given up on our son I feel I'm going through this by myself. I finally texted him and asked was it the autism that scared him he didn't text back so I said I will be here for you and we love you. I have cried for 3 days straight and for hours at a time I mean on the floor pulling my hair screaming and crying I'm so heart broken I can't function I can't eat I can't sleep I am beyond hurt I don't know what to do please help me.... Everyone has told me to leave him alone and move on but I can't and that's not what I want to hear. I've cried so much my face burns when another tear falls down... Please I've prayed like no other I've yelled and talked to God I'm loosing it. I know I should have let him come home when he asked. We work at the same job I hurt seeing him walk past like he dose t know me. I assume this woman works with us all he told me was he didn't know her but he sees her everyday and he wrote her on Facebook.
