If my husband were frequently hugging another woman who I was well aware regarded him as her best friend asnd would like him to be more than that - well I don't think I would be very responsive when he hugged me either.
If I thought that he shared the "other woman's" desire, I would either end the friendship he and I had with that woman, or I would end our marriage.
As she doesn't seem to be doing either of these things, I think you can assume that she knows perfectly well that he doesn't look on you in the way that you would like - and it is very likely that they have discussed the situation and decided to ignore it, perhaps they even pity you a bit, being lonely and not having a man of your own.
Go out more with other people, female and male - there are lots of men out there who are feeling as lonely as you, who don't have wives to complicate a relationship. No need to start up a romance with anyone - just get more variety of male input in your life.
