The marauders imagines and preferences

{What they do when they're jealous}

<Sirius>

Sirius doesn't get jealous much believe it or not. He trusts you and so he knows you will always come back to him howver if someone is talking to you however if someone if flirting with you and won't leave when you say no, he will come behind you, wrap his arms around your shoulders and make direct eye contact with the guy talking to you until he leaves.
If the guy still doesn't get the warning, Sirius will just start making out with you.

<James>

James can get very jealous very quickly. Although he knows you won't leave him, he still gets jealous and will become very clingy. If your talking to a guy, he will wrap his arms around you and try get your attention, disctracting you from the person you were talking to.
If you don't get distracted, he will start whispering cute (and dirty) things in your ear until you finally give him the attention.

<Remus>

Remus gets very insecure when you talk to other guys, he fears you will leave him for someone better so if you talk to someone, he will get rather quiet until you notice. Luckily, you understand why he feels this way so you will reassure him that you love him and only him.

<Peter>

Peter gets quite jealous when you talk to guys much more attractive than him so he will get quite cranky until you confront him and assure him you won't leave him.
