Ask all the questions you want. I don't mind because I was where you are now. I know about the good days and bad days. It will get better. Everyone used to tell me that and I couldn't see it getting better but it did.
I found out when my h came home he didn't spend as much time with the ow as I thought. At first he did then the newness wore off and she didn't want to do things with him anymore. All she wanted to do is drink. So it goes to show you that what we think and what actually happens doesn't always ring true.
Right now it is ALL about him. Yes there are probably things that you need to work on, just as I did, but it is his issues he needs to deal with. Just be patient.
My S used to come to my rescue too. He and his friend would take me out to clubs and we would have a great time. It got me out and away from things for a while. I am glad your D helped you out!!!!!
