Help!

Dear Joana,

I'm writing because I've got a problem, I don't know what to do.

Three months ago, Quim introduced me his friend Jack. My first impression was that he was a nice man, and he had a good character, he was a real gentleman, I thought that we had a lot in common.

Firstly, he asked me to go out, but only as friends. We went to a restaurant, a bar... Then, I started to feel that we were more than friends. There our relationship started.

Now, two months  later, my feelings for him don't exist, I know that he's a good and romantic guy, but I think it's better to split up with him. I don't get on well with him.

I need advice, help me please. What do you think I should do?

Your best friend, Alba
