I am going out on a limb here by asking you to really think about the question you just asked.
If you hated someone or disliked someone, would you really want to spend time with them by inviting them to go to an event with you? The answer would be no, of course not.
You would only ask someone to go to an event with you if you liked them. Therefore, I think it's safe to assume that the person asking you to go likes you.
