The question was, “What does it mean if a guy gets jealous of me liking another guy?”

A psychologist answered with this here...

It means he likes you, and it means that you are playing a game. You may not be consciously aware that you are playing the game, but that doesn’t matter, it is hurting you and him both.

It is time for you to quit playing. Decide if you want him or not.

If you do, don’t give him hints. Go up to him and tell him “I know you like me, and I like you, so let’s do something together.” Then you call him and make plans.

If you don’t, don’t give hints, and don’t jerk him around any more. Go up to him and tell him “I think you like me, but I don’t like you that way. I never will and nothing will ever change that. I won’t be mean to you, and I hope you won’t be mean to me, but let’s not even try to be friends.” Then do what you promised.

Time to shit or get off the pot, girl.
