He might tell you he loves her, but I don't believe it. I also think that he still loves you. Something went wrong in your marriage, and he decided to cheat. It's not your fault. What he should have done was bring his needs to your attention, and try to work it out with you. I know that it's hurting you really bad the fact that he keeps telling you that he loves her. I know it's hard, but you need to let him be. He knows that he's hurting you. I really think that you should leave him alone, because he needs to know that your not going to put up with his bs. He's really being a jerk. I think he has some nerve even bringing that woman into your house that you have shared with your husband. You might want to consider therapy if your not in therapy. If he came back to you now, your still need to work out the hurt. This is one of those things that is going to leave a scar. Your never going to forget it. Either way the damage is done, and your still going to need to get over the hurt, and it's not going to happen over night. Believe me when I tell you it's not your fault. Don't let him tell you it's your fault either. You deserve better then this.
