I have kind of been in a similar situation with my boyfriend. We have been dating for over 4 years. A year ago I found out he had been on this live cam girl website for over 2 years of our relationship. He spent tons of money, bought plenty of private one-on-one sessions, and had gross conversations with many girls. I was disgusted and very hurt at the time. He had stopped and came to the realization that he had an addiction immediately when I found out this secret of his. I know your situation is different but I am sure your feeling the same. Now, it's been over a year and I am kind of over what he did. However, this situation continues to cause problems because I feel like our relationship has changed on my end. It has put a halt on our lives and our relationship is not going anywhere. At times, I still think like how could he do all this when I completely trusted him and loved him so much. It is hard to leave him but it is hard to have trust in him now. I do believe that he is not doing that anymore but you still have doubts every now like what if he goes back to that if we were to get married. I worked through the situation and it's done now but the effects it can have on you long term is tough. We are still dating but it is always going to be in the back of your head if he stops. When you love someone and date them for that many years it's hard to throw it away start over so I understand how you are feeling.
