Recently divorced with a boyfriend who cheats on me. What should I do? :(?

Hello and thank you for taking the time out and listening to me. Well I'm a recently divorced (as of last year) young lady (younger than 30) who has a new boyfriend of almost 4 months. Unfortunately, my husband and I divorced because he simply no longer wanted to be married. Of course I was hurt and heartbroken, but I eventually moved forward. But this time, it may have been for the wrong guy. I met my new boyfriend at work. He had been working there for over 2 years and i just started. We hit it off quickly. He's extremely handsome man, so I was flattered when I found out he was interested in me. We started to date and things went well. Unfortualey, things started to unravel when I found out that he's had sex with 3 other different women at my job, and has talked to countless others. Not to mention that there was a young lady who he had sex with at the same time on the same day that we've once had sex. I actually found this out from her. When confronting him about it, he says to me "why should I even tell you these things when all it's going to do is hurt you and make you upset. Men will be men. I really love you but us men are just stupid". I just don't know what to do. He says he loves me but there are other women in life. He tells me I should just give him time to rid all of the women he has. Is he telling the truth? Should I believe him? Please help me :(
