Do you marry a man that has stated he would cheat on his wife if he knew he could get away with it .

I been dating a man for 3 years he asked me to marry him. But I have a horrible jealous side because he has said he would cheat if given the chance to get some strange, if he thought he wouldnt get caught. I have snooped on his phone to see if he was talking to another woman. I was wrong for snooping but can you trust a man that says he will cheat if given the change to get strange without getting caught????????????
