Will he leave me.

I am so scared my SO is going to leave me he is acting different when he comes home from work I would get a hug and a kiss but the past few days I have not gotten anything. He use to wrap is arms round me and just hold me I miss being close to him it not even about sex but him just touching me not in a sexual way. edit it as been more than a week I have tried been the one who hugs him he pulls a way and then I can't get a kiss.
