Aries men may have their attention diverted to other women when there is an opportunity. They may not resist one-night infidelity too much because they consider love and sexual desire as separate things.

However, feelings towards a serious girlfriend are unlikely to waver, and the possibility of Aries men cheating seriously is low. If approached by a proactive woman or in a situation where alone with a woman, if the relationship with his girlfriend is fulfilling, he is unlikely to feel like cheating.
