Feeling like such a hyprocrite

I woke up this morning wanting to start bawling over Shelley.  I feel I shouldn't be feeling like this.  I avoided her.  I wanted to make sure I didn't get put in a position I didn't want to be in.  I feel so guilty.  Should I be?  Wanting to do the right should not be something to feel guilty about.  I didn't want to let things get to where her husband acted out towards me.  She used to babysit my son and while she was at the store I came to pick him up.  I didn't know he was there with the boys.  He answered the door in his underwear. Maybe he would have done that to whoever was at the door but it seems really strange to me.  And once while she was in the tub he called me on the phone and we talked for an hour.  I was folding laundry and didn't realize how long we were on the phone.  He was telling me his lifes story.  I just felt like if things kept going something was going happen.  I did not want to hurt her by having to tell her he made a pass at me.  So I walked away.  Was it the wrong thing? I thought if I prevented there from being anything to tell that was the right thing.  Could I have handle things in a better way.  I thought I did the right thing.  I could really use some feedback.
