I am having an affair with a married woman

Recently a few months back I met a woman . Me being single I put the moves on her not knowing she was out with friends for a celebration of marriage to another man . We ended up back at my place and so on . The next morning she left and we continued to talk and eventually met again and again . She ended up telling me she was getting married and I was taken back for a second but also thought I could continue and everything would be ok . I didn't know the man . I have no strings attached on my side and she obviously was looking elsewhere for her fulfilment . Over this short time I asked her why and she said she has never met anyone quite like me and we connected very well . To the point of her saying I love you . She has told me that he is an over the road truck driver and that she needs someone who is going to be there for her . I guess I used that as an excuse to keep the affair going and we only saw each other more . It strengthened the bond between us and yes I do care for her and I am in love . During this time I got to meet the other guy when we went to a concert and I recognized him as I may have ran into him before and he wanted to be friends . I pretty much kept it simple and he knows me as the friend of his wife . This is where I start to really feel like this is crazy . A few days back he started to feel that something is going on between us . I pretty much told her that if she isn't happy with him tell him that he needs to be around more . I also said that as of now it's just a matter of time before they divorce sue to him not trusting and her not having her husband around at all . I know this isn't my place to get involved but I feel it's the truth . She said she doesn't want to cut this off but slow it down . Mind you that she also works with me and she is my car pool person . It is hard to cut something off when you do care and falling in love . I know this is a mistake but it happened . What do I do next ?
