relationship

Jealously:
So I introduced my boyfriend and my friend together at the time I wasn't jealous but lately I feel left out. They talk all the time and whenever I try to talk to him he's either busy or too tired. Then saw on his phone that on his contact list he had her name with emojis and fancy font. Then when I looked at my contact I just see "Sam". This year they have a bunch of classes together and I don't have a single class with my boyfriend or my friend. I feel so stupid because I don't know how to talk to him about this because it sounds like I'm crazy jealous. I just wish they never met but is that too selfish? Ugh I wish my jealousy would just go away 
So update: I talked to him and he was just talking to her about how he should ask me to homecoming! He even let me read their texts so it's all Gucci
