I agree with solitas777 if aries is deeply in love with you he will not cheat The romantic idea of being faithful to one person forever is appealing to Aries because of their strong sense of romance. However, if things go bad he or she may stray, in search of more attention, excitement and love.
when i was in love with my ex Sagittarius it last it for 5 years until she discarded me like a used chewing gum with no flavor when we were together it never crossed my mind to cheat on her, but i would flirt with other girls and sometimes give more than friendly hug or kiss but that was it...its not like she was an angel her self and we always had a good laugh about it and made us even closer so aries man do not cheat as long they are in love with a capitol L
this days that would be me, but the guilt is the only thing that stops me form going all the way if it wasnt for my stupid guilt you all would haveto lock up your girlfreinds, moms, and daughters, lol but dont worry you can sleep at night.....for now at least,
