I told my crush that I liked him and he likes me back! But one day my friend did confessions on Facebook. One of her confessions was that she didn't kiss anyone. He saw it and got all upset and I don't know why. I told him that she meant lips to lips kiss not lips to cheek. They used to date but broke up. They are friends now but I still don't understand why he was so upset. According to him his feelings for me are stronger than for his ex. What do I do about this problem.

What exactly is the problem?

He acted all sad when she said that she enver kissed anyone and I thought he was over her. Now I'm not so sure.

Is this the library guy?

Would you not post two separate post if they are about the same person. It gets really confusing.

You may very well be a rebound. He may still likes the girl, so you are up a creek.
I don't know. Why don't you ask him.

You can have a total conmunication with your boyfriend. Then things will be better. Good luck.

For him to feel upset about it shows me that he may have feelings for her...

Your best bet is to simply ask him.
