The only way you can get her trust back is get the help that you said you are going to get and slowly rebuild her trust through your actions, she has to feel she can trust you not to download anymore porn and she probably felt that you didn't find her attractive anymore and would rather watch young women on the Internet rather than have sex with her. It will be a process that you will have to go through I think once she sees that you truly are seeking help for this porn addiction she will learn to trust you again. Explain to her that you have taken her for granted and for that you are sorry. Show her that your appreciate her once in a while buy her flowers, take her to dinner, making her a romantic dinner at home she just wants to know that you appreciate her as your wife and wants to feel wanted again. Explain that the fact that you lost you job for that 6 months made you feel like you weren't doing your part as a husband and the porn may have been a way for you to feel like manly again and that it had nothing to do with her and that you love her and cherish her and you want to show her that.
Your wife may have felt like the porn became your wife instead of her, let her know that isn't true give her some of her confidence back that the porn may have taken away. Deleting the porn and getting rid of the Playboy magazine is a start be still think about getting the counseling to help you better understand why you needed to turn to porn also consider Marriage counseling to help you get your marriage back on track and may even make it much stronger.
All you can do is give her whatever she asks for this will show her that you really are trying and you really do want what is best for her, she is angry right now and I don't think she think you mean it when you said it because she thinks she wasn't enough for you and that is why you turned to porn. Just give her some time give it about a week and then try saying it in the morning before you leave again and see what her response is then, if she doesn't respond to that but doesn't get mad either then I would continue to say it every morning before you left for work also you could try getting up early making her breakfast and then write her a note saying I know I don't deserve your love right now but I didn't want to continue on not saying I love you in the mornings before I left in case something were to happen to either of us this could make her think how important life is and telling someone you love how you feel every minute of the day. For the first week you will have to walk on eggshells but show her you are willing to get the help you need and then after you start counseling ask her to possibly start Marriage counseling also.
I don't think you staying at your fathers home is a good idea then she may think that you are over there looking at porn and it may make things worse, you need to stay there and face this head on right now she is hurt and upset and this is her way of getting back at you for making her feel inadequate she doesn't really want to lose you or she would have made you move out when she first found out about everything being away from her now may not be to your benefit because she may realize that she can get just as much attention being alone. You need to show her that you want this marriage to work and be stronger than it has been, try buying her flowers and on the card put "Words nor actions could ever show you how much I love you and I'm sorry." Something to that affect let her know that this is tearing you up inside finally be honest with your feelings and let her back in to your life, she may feel you put her on the outside looking in and chose porn over her, show her that isn't true.
Right now she may not care and may be a little depressed because of not feeling wanted but don't hold that against her only time will heal those wounds, you leaving will not heal that pain for her. She may be showing you that she has shut down but she still feels something or this would not of hurt her so bad but what you have to do is make an effort and fight for you marriage. You should check into the counseling as soon as humanly possible this will also show her that you are taking the steps you need to gain her trust back. If she said yes as far as the father home is concerned you should tell her that you don't feel comfortable leaving her like this and if she still wants you to leave then respect her wishes but continue to try to get her trust back and start with the flowers and then check for a reputable counselor in your area. Show her that SHE and not the porn is the only thing that matters in your life.
