Please don't judge me just asking advice

So I have been with my husband for 7 years and he is the only real relationship I have been in and was my first but I feel like maybe I rushed into things and I didn't experience life and relationships, now there this other guy that am interested in and we flirt all the time and this guy wants to go forward more then a friendship , I love my husband but I just feel really confused .. any advice , we also work together so it makes it really hard (I have not cheated on my husband ) please no rude comments
