Confused and conflicted?

So I been with this guy 2 times previously in a realtionship. And he has recently just came back in my life but this time I'm married. He and I have been fooling around for close to 2 months. I love my husband but have had no intimacy with him for close to a year. So I'm liking qhat has been going on. So my big question is should I leave my husband or work it out and leave the other guy alone?
