It's a question

So I really liked this girl but was too scared to come out to my family and friends and she ended up dating a guy for awhile. (She's had made it clear that she was into me before) Then, they broke up and she came over specifically to tell me th at she was single again. We spent a little time together and I didn't make a move or tell her that I still have really strong feelings for her and now she's back with her ex. Should I confess my feelings to her even though she has a boyfriend right now? I'm worried that's disrespectful to her relationship
