Jealousy from suggestive look

[Gylaran]

My sim have great partner he want to spend his life with, but i ran into a problem. Whenever some woman talk to me and they give me suggestive look, i hit ignore it, mainly when my love is around. The problem is even when i ignore it, my love send jealousy burst towards me and is saddened the next hours. Is this normal? Can i set something to change it, or do i only need to add them a Polyamory trait to stop this? It is annoying, though it's realistic as i personally had gf who thoughts that i am to blame when some girl try to flirt with me.
