Rebound?

So I’ve been seeing this guy at work for over a month. He is great and everything I’d want in a boyfriend, plus he is super attractive. No one knows we are together as the relationship is still very new and we both agree we didn’t want everyone knowing our business because relations with colleagues can get sticky at times. I always told myself I would avoid dating guys I work with and here we are...

However, I just recently also came out of a long term relationship (5years) and realised I didn’t give myself time to heal before jumping into this new relationship. I don’t want to break up with this new guy but I just think things are moving way to fast. I want to talk to him about it but I don’t want him to think he is just a rebound because I really do like him.

Help!!
