what are the signs of infidelity in the relationship?

Answer 1

Not spending quality time

Emotionally distant

If they feel guilty they can't look at you in the eyes

If they always sleep facing you if they are cheating the will face the opposite way from you

Don't answer their phone when you call

Or always have their phone on silent whenever they are around you

Answer 2

Not calling or being there when he is supposed to. New cologne, clothes, especially underwear, maybe new hairstyle, when he does call, the story sounds phoney. When he is with you, may be distracted, keeps looking at cell phone, and then when there is actually infidelity - sometimes in your heart, you just "know it"!!
