Open Question: What should i do about my bf?

[feedcrawler]

If you have read my other questions you will understand what is going on. He apoligized for everything before and deleted all the girls from his facebook.But the last couple days hes been re-adding them and checking out there pictures. I also found an old msn convo from the summer him and a girl he worked with would sneek off to the break room and he would tickle play with her feet (foot fetish) and they constantly hugged. He could have confessed to me this when he was sorry about all the other things. This will be the 3rd time it has been an issue. What can i do to get him to stop and for me to forgive him forever? When i asked him last time why he did these things he said that he honestly didnt know?
