I’ll be honest here, I was near the end of my first long term relationship and I joined Facebook. He did not have an account and I used it as private safe place to try and see what other men were out there. I am saying I did this when I knew things were over, our once healthy relationship was not healthy anymore, and low and behold I met lots of nice interesting men on it. Now I’m just using my example to make a point… I still have a facebook, my fiancé is not only my friend but we are both listed as engaged to each other on it; we have lots of mutual friends. Nothing is secret and I don’t have to be accused of snooping if I read his wall. There is only one reason you are blocked, it’s because he wants to keep something secret from you, and just like I did. If you have a secure healthy relationship facebook should not a secret world for either of you. He has a history, you caught him red handed, this is not a man who wants to marry you, it’s a man who wants his cake and eat it to, either that or he’s straight up looking for a replacement. There are lots of men out there who will treat you better, and who will love you and not play games with you and other girls. You need to just get out of this situation, the more you stick with it the more you will get hurt.
