While in a relationship is send these emojis cheating (❤️😘😍😗😉😻💋👅)

Also my partner was a single dad But the ex won't/ wouldn't let him see his daughter. Then he got with me and I'm expecting my baby in October yet he is telling someone he is a single dad yet the chick asked him y is he in a relationship on Facebook with me and being tagged in baby posts. Wtf should I do I've stayed loyal never spoken or done anything but he does accuse me of it all the time. Wtf should I do is it cheating or am I over reacting
