I am sorry for the pain this is causing you. You still have hopes because you are genuinely in love with him and unfortunately, although he is unworthy of you being in love with him, your feelings don't change that quickly. I still feel that you should leave him for all of the reasons I mentioned before....remember because you are genuinely in love with him that is the only reason you think that there could be hope, however, even today he still was not honest with you and did not take the initiative to tell you anything- another huge red flag. I suggest to also do the following because you are worth it:
1. Get a positive support system in place for yourself which includes loved ones and friends you can trust and share this extremely painful experience with and who will also help you through it.
2. You are dealing with various normal emotions due to being separated from someone you were once so close to, therefore, if possible, I recommend going to see a therapist, counselor, etc., in person on a weekly basis to help you deal with this (-especially any guilt, hurt, confusion, frustration, anger, etc. that you may naturally feel). If you are religious, your place of worship may have free counseling available (-many churches have free counseling).
3. Write down how you feel in a journal. Then close out each writing session by meditating: close your eyes, breathe in deeply and exhale. At the same time think of something peaceful. For example: a bright blue ocean with deep rich blue waves gently whispering against the beach. Meditating will help you through this difficult time and it will also help you to heal. It will take some time, but you will get through this very painful and difficult time if you do the above steps.

I know it doesn't seem like it now, but slowly and surely you will be able to overcome this.
