Cancer Man and Wayyyyyy Too Many Females

My cancer man is surrounded by way too many female friends and exes. I try not to let it weird me out but its getting me angry now. He constantly stays checking in on them. Im usually not insecure but he's bringing it out of me. Do cancer men usually surround themselves with women?

I have the same problem too...I'm the jealous type...I told him about it and he said they're just friends...
but i do know cancers have a good memory and carry their past with them..

I want to know what other cancers do too...
